Potassium octachlorodimolybdate

Potassium octachlorodimolybdate (systematically named potassium bis(tetrachloromolybdate)(Mo–Mo)(4−)) is an inorganic compound with the chemical formula K4Mo2Cl8 (also written as K4[Cl4MoMoCl4]). It is known as a red-coloured, microcrystalline solid. The anion is of historic interest as one of the earliest illustrations of a quadruple bonding. The salt is usually obtained as the pink-coloured dihydrate. The compound is prepared in two steps from molybdenum hexacarbonyl: 2 Mo(CO)6 + 4 HO2CCH3 → Mo2(O2CCH3)4 + 2 H2 + 12 COMo2(O2CCH3)4 + 4 HCl + 4 KCl → K4Mo2Cl8 + 4 HO2CCH3
