Molybdenum ( IV) chloride is an inorganic chemical compound of molybdenum from the group of chlorides.

Production and representation

Molybdenum ( IV) chloride can be obtained by reaction of molybdenum ( V) chloride with benzene, molybdenum ( III) chloride or tetrachlorethylene are obtained.

Properties

Molybdenum (IV ) chloride is a paramagnetic, light, air and moisture sensitive black powder or black - brown, hexagonal columns. It is extremely susceptible to hydrolysis and dissolves without residue with yellow to reddish brown in water, ethanol and ether. When heated above 180 ° C in vacuum, it is with partial decomposition in molybdenum (III ) chloride and molybdenum (V ) chloride volatile. It has a trigonal crystal structure with space group P31c (a = 605.8 pm, c = 1167.4 pm ). The compound ( α - form with chains of trans- edge-sharing octahedra MoCl6 ) converts to 250 ° C in the β -shape around which consists of rings of six cis- edge-sharing octahedra MoCl6.
