Abstract

Abstract : The synthesis, characterization and computational analysis of a range of bis(iminophosphoranyl)phosphide (BIPP ) group 4 and coinage metals complexes is reported. White phosphorus was used to install the central phosphorus atom. Abstract : The synthesis and characterization of a range of bis(iminophosphoranyl)phosphide (BIPP ) group 4 and coinage metals complexes is reported. BIPP ligands bind group 4 metals in a pseudo fac -fashion, and the central phosphorus atom enables the formation of d 0 –d 10 heterobimetallic complexes. Various DFT computational tools (including AIM, ELF and NCI) show that the phosphorus–metal interaction is either electrostatic (Ti) or dative (Au, Cu). A bridged homobimetallic Cu–Cu complex was also prepared and its spectroscopic properties were investigated. The theoretical analysis of the P–P bond in BIPP complexes reveals that (i) BIPP are closely related to ambiphilic triphosphenium (TP ) cations; (ii) the P–P bonds are normal covalent ( i.e. not dative) in both BIPP and TP .
