Abstract
Reaction of the molybdenum(III) compound Mo2O2Cl2(H2O)6 with ligands, L, gave complexes Mo2O2Cl2(H2O)xLy[L = 2,2′-bipyridyl and 4,4′-dimethyl-2,2′-bipyridyl (x= 2, y= 2), pyrrole and pyridazine (x= 4, y= 2), pyridine (x= 4, y= 3)], Mo2O2(H2O)xLy[L = acetylacetonate (x= 4, y= 2) and tartrate (2-)(x= 6, y= 1)], and an oxalato-complex Mo4O3(C2O4)3(H2O)12. The complexes are formulated and structures proposed on the basis of analyses and physical measurements. The binuclear complexes contain the di-µ-oxo-dimolybdenum(III) group, MoO2Mo, and the tetrameric oxalato-complex contains µ-hydroxo-µ-oxo-dimolybdenum groups, Mo(OH)OMo, linked by bridging oxalate. Earlier formulations of some of the complexes with terminal oxygen bonded to molybdenum are shown to be incorrect.Keywords
