Silver(i) complexes of N-thiophosphorylated bis(iminophosphorane) ligands: From monomers to polymers

Abstract

Treatment of diphosphines Ph2P(CH2)nPPh2 (n = 1, 2, 4, 6) and [Fe(η5-C5H4PR′2)2] (R′ = Ph, iPr) with a two-fold excess of (RO)2P([double bond, length as m-dash]S)N3 (R = Et, Ph) results in the high-yield formation of the N-thiophosphorylated bis(iminophosphorane) derivatives (CH2)n[P{[double bond, length as m-dash]NP([double bond, length as m-dash]S)(OR)2}Ph2]2 and Fe(η5-C5H4[P{[double bond, length as m-dash]NP([double bond, length as m-dash]S)(OR)2}R′2])2, respectively. The reactions of these ligands with AgSbF6 in a 1 : 1 molar ratio have been investigated. The resulting silver(I) complexes, derived from the selective coordination of the P[double bond, length as m-dash]S units, have been characterized by IR, NMR and MS (FAB) spectroscopy and, in selected cases, by X-ray crystallography. Monomeric, dimeric and polymeric solid-state structures, depending on the nature of the ligand backbone, have been found.
