Abstract

The imidodiphosphinoselenido complexes of V(IV), V(III), and Cr(III), [VO{N(SePPh₂)₂}₂]·CH₂Cl₂ (1), [V{N(SePPh₂)₂}₃]· CH₂Cl₂ (2), and [Cr{N(SePPh₂)₂}₃]·CH₂Cl₂ (3), have been prepared from the reaction between VCl₃(THF)₃ (1 and 2) or CrCl₂ (3) and K[N(SePPh₂)₂] in CH₂Cl₂. These compounds have been characterized by single-crystal X-ray diffraction and spectroscopic techniques as well as by a magnetic susceptibility measurement for 3. In each of these compounds the [N(SePPh₂)₂]^- ligand exhibits an Se, Se′-bonding chelation to the metal center. In 1, two ligands are coordinated to a VO²⁺ unit to afford a pyramidal environment about V; in 2 and 3, three ligands are coordinated to each metal center to afford an octahedral geometry.
