An Ambiphilic Phosphide with Three Different Coordination Modes to Group 7–10 Metals

Résumé

Phosphide anions PX 2 -with electron-withdrawing substituents display ambiphilic properties. The use of P(V) thiophosphorane substituents enables the coordination of the resulting bis(thiophosphoranyl)phosphide anion (BTPP = L) to a variety of transition metals from groups 7 to 10. A series of homoleptic and heteroleptic complexes was synthesized and X-ray diffraction analysis revealed that, depending on the metal, L may adopt three coordination modes (κ 3 -(S, P, S); κ 2 -(S, S); κ 2 -(S, P)) supporting three distinct geometries (octahedral; tetrahedral; square planar). Complex L 2 Co displays Single Molecule Magnet (SMM) properties, and complex LRh(COD) (COD = 1,5cyclooctadiene) catalyzes the hydrosilylation of terminal alkynes.
