SYNTHESIS AND PHYSICOCHEMICAL INVESTIGATION OF SOME MIXED-LIGAND CYANONITROSYL (MO(NO)2)6 COMPLEXES OF MOLYBDENUM WITH SOME ANILINE DERIVATIVES

Novel hexa-coordinated, mixed-ligand cyanonitrosyl complexes of molybd enum(0) of the composition [Mo(NO)2(CN)2(L)2].2H2O (where L = aniline derivatives. viz., o underbar-, m underbar-, p underbar-anisidine/phen etidine, N-methylaniline or N,N-dimethylaniline) have been prepared in the solid state by the interaction of (Mo(NO)2(CN)4]2- with the appro priate aniline derivative L. The resulting compounds have been charact erized by elemental analyses, molar conductances, magnetic measurement s and infra-red spectral studies. An octahedral structure is suggested for the complexes. Molybdenum(0) has a low-spin {Mo(NO)2}6 electron c onfiguration1 in these complexes.
