Ammonium Titanium(4+) Fluoride (2:1:6)

Ammonium-titanium (IV) fluoride (2:1:6), its chemical structure is also. This compound is composed of ammonium ions ($NH_ {4 }^{+}$）、 titanium (IV) ions ($Ti ^ {4 +} $) and fluoride ions ($F ^ {-} $) in a ratio of two to one to six.
First, ammonium ions, which are cations with a unit positive charge, are formed by combining ammonia molecules ($NH_ {3} $) with a proton ($H ^ {+} $). In the crystal structure, ammonium ions can often be regarded as spherical cations, interacting with surrounding ions through ionic bonds.
and titanium (IV) ions, which are positive tetravalent in compounds. Titanium atoms have twenty-two electrons, and when $Ti ^ {4 +} $is formed, the outermost four electrons are lost. This ion can exhibit a specific coordination geometry in compounds due to its electron arrangement.
Furthermore, fluorine ions, which are anions with a unit negative charge. Fluorine is extremely electronegative and easily attracts electrons in compounds.
In this (2:1:6) compound, two ammonium ions and one titanium (IV) ion are combined with six fluorine ions. From the structural point of view, fluoride ions coordinate around titanium (IV) ions to form a specific coordination polyhedron. In the common coordination mode, fluoride ions may form an octahedral coordination environment surrounding titanium (IV) ions, that is, titanium (IV) ions occupy the center, and six fluoride ions are distributed at the apex of the octahedron, and are connected to titanium (IV) ions through coordination bonds.
And ammonium ions are distributed in the structural gap composed of $[TiF_ {6}] ^ {2 -} $anions, and interact with $[TiF_ {6}] ^ {2 -} $anions through ionic bonds to maintain the stability of the entire crystal structure. In this way, the ions together form the unique chemical structure of ammonium-titanium (IV) fluoride (2:1:6) by virtue of their charge and spatial arrangement.

To prepare ammonium-titanium hexafluoride (2:1:6), the method is as follows:
First take an appropriate amount of titanium-containing compounds, such as titanium tetrachloride ($TiCl_ {4} $), because titanium is in a tetravalent state and is suitable for use. Place it in a special reaction vessel that can withstand the corresponding chemical reaction conditions, such as corrosion resistance and temperature control.
Take a sufficient amount of hydrofluoric acid ($HF $) and slowly add it. Hydrofluoric acid and titanium tetrachloride can react, and this reaction is very critical, which is related to whether fluoride ions can successfully combine with titanium ions. The reaction formula is roughly: $TiCl_ {4} + 6HF\ longrightarrow H_ {2} TiF_ {6} + 4HCl $to form fluorotitanic acid ($H_ {2} TiF_ {6} $). This process requires careful temperature control, generally maintained at a moderate low temperature, about 0 dollars - 10 ^ {\ circ} C $, to prevent side reactions.
After the formation of fluorotitanic acid, add an appropriate amount of ammonium salt, such as ammonium fluoride ($NH_ {4} F $). The ammonium ion binds to the fluorotitanate ion to obtain the target product ammonium titanium hexafluoride (2 dollars (NH_ {4}) F\ cdot TiF_ {4}\ cdot 6H_ {2} O $). The reaction formula is: $2NH_ {4} F + H_ {2} TiF_ {6}\ longrightarrow (NH_ {4}) _ {2} TiF_ {6} + 2HF $. This step also needs to pay attention to the reaction conditions, such as reaction time, stirring degree, etc. After the reaction, after crystallization, filtration, washing, drying and other processes, pure ammonium titanium hexafluoride can be obtained. The whole process must strictly follow the operating procedures and pay attention to safety, because the reagents used are corrosive or toxic.

The physical and chemical properties of ammonium titanium (IV) fluoride (2:1:6), that is, (NH) 2O TiF, are as follows:
Looking at its physical properties, (NH) 2O TiF is mostly white crystalline powder under normal conditions, with a fine and uniform quality. It is quite stable at room temperature and is not easy to deliquescent in air. Due to its relatively tight lattice structure, it is difficult for water molecules to invade the lattice gap and combine with it. Its density can be obtained by measurement, and the value is about [X] g/cm ³. This density makes this substance have its unique performance in many application scenarios. In solution systems, it can be separated from other substances with different densities according to this property.
When it comes to solubility, (NH) -2 TiF is soluble in water and rapidly dissociates in water to form ammonium ion (NH) and hexafluorotitanate ion (TiF ²). This dissolution process is accompanied by a certain heat change, which is an endothermic reaction, and the water temperature decreases slightly. Its solubility increases significantly with the increase of temperature. Every time the temperature increases [X] ° C, the solubility increases by about [X] g/100g water. This property has important applications in its crystallization and purification processes.
As for the chemical properties, the aqueous solution of (NH) -2 TiF is acidic, which is due to the hydrolysis of ammonium ions. Ammonium ions combine with water-ionized hydroxide ions to increase the concentration of hydrogen ions in the solution, and the pH value is about [X]. When exposed to strong bases, ammonium ions react with them to form ammonia gas to escape.
In addition, the properties of hexafluorotitanate ions are relatively stable, but under certain conditions, in case of strong reducing agents, titanium (IV) can be reduced to a low-priced state. And (NH) -2 TiF reacts with some metal salt solutions to form new double salt precipitation, which can be used for material preparation and separation.
(NH) 2O TiF is also unstable when heated. When the temperature rises to about [X] ° C, it begins to decompose, generating products such as ammonia, hydrogen fluoride gas, and titanium fluoride. This thermal decomposition property can be used in materials synthesis and other fields.

Ammonium titanium (IV) fluoride (2:1:6), that is, (NH) -2 TiF, when using, there are many precautions and need to be treated with caution.
First, it is related to safety protection. This compound is toxic and corrosive, and can cause burns and irritation to the human body. Therefore, when using it, it is necessary to adapt protective equipment, such as protective gloves, goggles and protective clothing, to prevent it from coming into direct contact with the skin and eyes. In case of inadvertent contact, rinse with plenty of water immediately and seek medical attention according to the injury.
Second, about storage conditions. Store it in a cool, dry and well-ventilated place, away from fire and heat sources. Because it is quite sensitive to humidity and temperature, humid or high temperature environment is easy to cause it to deteriorate, affecting the performance of use. And it should be stored separately from oxidants, acids, etc., to avoid reactions.
Third, the operating specifications during use cannot be ignored. When configuring the solution, it should be slowly added to the solvent according to a specific ratio and sequence, and stirred continuously to prevent adverse reactions caused by excessive local concentration. At the same time, the operation should be carried out in a fume hood. Because the reaction process may produce harmful gases, good ventilation can be discharged in time to ensure the safety of operators.
Fourth, post-treatment should also be appropriate. The remaining reagents should not be discarded at will, and should be treated harmlessly in accordance with relevant regulations. For the waste generated by the experiment, it needs to be sorted and collected, and disposed of according to a specific process to prevent environmental pollution.
In short, when using ammonium titanium (IV) fluoride (2:1:6), from safety protection, storage conditions to operating specifications and post-treatment, it is necessary to be rigorous. Do not be negligent in order to ensure the safety of the use process and achieve the desired effect.
