Ammonium hexachloroiridate(IV) is the inorganic compound with the formula (NH 4) 2 [IrCl 6].This dark red solid is the ammonium salt of the iridium(IV) complex [IrCl 6] 2−.It is a commercially important iridium compound, [1] one of the most common complexes of iridium(IV).
In a crystal structure the coordination geometry of an atom is the geometrical pattern of coordinating atoms where the definition of coordinating atoms depends on the bonding model used. [1] For example, in the rock salt ionic structure each sodium atom has six near neighbour chloride ions in an octahedral geometry and each chloride has ...

The respective C–O and C–N distances are 1.174(8) and 1.192(7) Å, consistent with the O=C=N − description. Ammonium cation [NH 4] + forms hydrogen bonds with cyanate anion O=C=N −, but to N, not to O. [1] The compound is notable as the precursor in the Wöhler synthesis of urea, an organic compound, from inorganic reactants. [2]
CuSO 4 (aq) + 4 NH 3 (aq) + 4 H 2 O → [Cu(NH 3) 4 (H 2 O) 2](OH) 2 (aq) + H 2 SO 4 (aq) Ammonia or ammonium ion when added to Nessler's reagent gives a brown color precipitate known as the iodide of Million's base in basic medium. Ammonium ion when added to chloroplatinic acid gives a yellow precipitate of ammonium hexachloroplatinate(IV).
One structure is trigonal bipyramidal molecular geometry type NH 5 molecule. Its nitrogen atom and hydrogen atoms are covalently bounded, and its symmetry group is D 3h. [1] Another predicted structure of nitrogen pentahydride is an ionic compound, composed of an ammonium ion and a hydride ion (NH 4 + H −). Until now, no one has synthesized ...
Ammonium iron(II) sulfate, or Mohr's salt, is the inorganic compound with the formula (NH 4) 2 SO 4 ·Fe(SO 4)·6H 2 O.Containing two different cations, Fe 2+ and NH + 4, it is classified as a double salt of ferrous sulfate and ammonium sulfate.
The anion [Ce(NO 3) 6] 2− is generated by dissolving Ce 2 O 3 in hot and concentrated nitric acid (HNO 3). [2] The salt consists of the hexanitratocerate(IV) anion [Ce(NO 3) 6] 2− and a pair of ammonium cations NH + 4. The ammonium ions are not involved in the oxidising reactions of this salt.
