Abstrakt: Dibromotetracarbonylmolybdenum, Mo(CO)4Br2, and the dihalotetracarbonyltungsten compounds, W(CO)4X2 (where X = Cl, Br), have been isolated and characterized. These highly reactive compounds are all diamagnetic. The trihalotetracarbonyl anions [M(CO)4X3]- (M = Mo, W) have been isolated as their tetraethylammonium salts from the parent halocarbonyls. These yellow diamagnetic compounds are the first tetracarbonyl derivatives to be prepared from the parent halocarbonyls.
