Abstract

Microcrystalline substances of the composition [MgX12Lg]X2, M = Nb,
Ta, X = Cl, Br, L = NH3, CH3CN, C5H5N, were prepared by the reaction of ethanolic solutions of [MgX12(C2H5OH)6]X2 with ammonia gas or simply by dissolving these clusters in acetonitrile or pyridine. The spectral data point to the occupancy of all octahedral coordination sites by nitrogen donor ligands.
