Synthesis and crystal structure of unprecedented phosphine adducts of d(1)-aryl imido-vanadium(IV) complexes
The reaction of the imido precursor [V(NAr)Cl-2](n) (1) (Ar = 2,6-i-Pr2C6H3) with 3 equiv of PMe2Ph yields the monomeric complex [V(=NAr)Cl-2(PMe2Ph)(2)] (2). Reacting 1 with 1.5 equiv of dmpe or 1 equiv of dppm affords the dimeric complexes [V(=NAr)Cl-2-(dmpe)](2)(mu-P,P'-dmpe) (3) and [V(=NAr)Cl-2(dPPM)](2) (4), respectively. Complexes 2-4 have been fully characterized by spectroscopic methods, magnetism studies, and X-ray crystallography.
