Ammonium hexachlororuthenate(IV), 99% is a high-purity inorganic compound with the formula (NH₄)₂[RuCl₆].

It is a crystalline salt, typically appearing as dark red or black crystals. The "99%" denotes its high purity, making it suitable for precise research and advanced synthetic applications.

Key Characteristics:

Oxidation State: The ruthenium in this complex is in the +4 oxidation state (hence the "IV").
Structure: It features the octahedral [RuCl₆]²⁻ anion, with ammonium (NH₄⁺) as the counter-cation.
Precursor Nature: Its primary value lies in being a convenient, soluble, and well-defined source of ruthenium(IV) for chemical synthesis. It's often a starting point for making other ruthenium complexes and materials.

Major Uses in Chemistry:

Precursor to Ruthenium Dioxide (RuO₂):

Electrocatalysts: For the oxygen evolution reaction (OER) in water splitting and chlor-alkali processes.
Thin Films & Coatings: For electrochemical capacitors (supercapacitors) and conductive layers.
Resistive Films: In microelectronics.
Upon thermal decomposition or controlled hydrolysis, it converts to ruthenium dioxide, a critically important material.
RuO₂ Uses:

Synthesis of Other Ruthenium Complexes:

Catalysis: Homogeneous catalysts for organic transformations (e.g., oxidation, hydrogenation).
Photochemistry & Photocatalysis: As potential dyes or catalysts in light-driven reactions.
Medicinal Chemistry: As potential anticancer agents (though other Ru complexes like KP1019 are more prominent).
Serves as a versatile starting material for preparing a wide range of ruthenium coordination compounds with different oxidation states (III, II) and ligands. These complexes are studied for:

Source of the [RuCl₆]²⁻ Ion in Research:

Used in fundamental studies of coordination chemistry, electron transfer processes, and the spectroscopic properties of octahedral metal-chloro complexes.

Material Science & Nanomaterial Synthesis:

As a precursor for the chemical vapor deposition (CVD) or solution-based synthesis of ruthenium-containing thin films and nanoparticles.

Analytical Chemistry:

Has been used historically as a standard or reagent in certain analytical techniques for ruthenium or related separations.

Important Handling Note:

This compound, like many ruthenium complexes, is toxic and should be handled with care. It can release hazardous fumes (e.g., RuO₄, a toxic, volatile oxide) under strong oxidizing conditions or when heated in air. Proper personal protective equipment (PPE) and fume hood use are essential.

In summary, Ammonium hexachlororuthenate(IV), 99%, is a high-purity inorganic salt primarily valued as a critical precursor for synthesizing technologically important materials like ruthenium dioxide and as a versatile starting point for advanced ruthenium chemistry in catalysis and research.
