Complex [Mo(NHNPh₂)(NNPh₂)Br₂(acac)], acac=acetylacetonate, reacts in acetonitrile with 1,10-phenanthroline, o-phen, and 2,2’-bipyridine, bpy, to afford complexes [Mo(NNPh₂)₂Br₂(o-phen)], I, and [Mo(NNPh₂)₂Br₂(bpy)], II. These complexes have been characterized by IR, UV-vis and ¹H NMR spectroscopies, and elemental analysis. The structure of complex I was solved by single crystal X-ray diffraction. The metal center has a distorted octahedral environment in which the diphenylhydrazido(2-) ligands occupy mutually cis positions but trans to the nitrogen atoms of the o-phen ligand. The bromo ligands occupy mutually trans positions.
