The reaction of the imido precursor [V(NAr)Cl2]n (1) (Ar = 2,6-i-Pr2C6H3) with 3 equiv of PMe2Ph yields the monomeric complex [V(NAr)Cl2(PMe2Ph)2] (2). Reacting 1 with 1.5 equiv of dmpe or 1 equiv of dppm affords the dimeric complexes [V(NAr)Cl2(dmpe)]2(μ-P,P‘-dmpe) (3) and [V(NAr)Cl2(dppm)]2 (4), respectively. Complexes 24 have been fully characterized by spectroscopic methods, magnetism studies, and X-ray crystallography.
