Abstract

The dichlorodioxido(4,4′-dimethoxycarbonyl-2,2′-bipyridyl)molybdenum(VI) complex was prepared from molybdenum(VI) dichloride dioxide and 4,4-dimethoxycarbonyl-2,2-bipyridyl in CH2Cl2 obtaining a clear green solution. The molybdenum complex was separated by precipitation with ethyl ether. The XRPD pattern for the new compound showed that the crystalline compound belongs to the monoclinic space group P21 /c (No 14) with refined unit-cell parameters a = 12.104(1) Å, b = 14.933 (2) Å, c = 11.010 (2) Å and ß = 115.409° (9). The volume of the unit cell is V = 1797.6 (3) Å3.
