Solid State Structure of cis-[W(CO)4(pip)(PPh3)

Abstract

The solid state structure of cis-[W(CO)4(PPh3)(pip)] (1) was determined by X-ray crystallography. cis-[W(CO)4(PPh3)(pip)] was synthesized by reaction of PPh3 with cis-[W(CO)4(pip)2] and isolated as yellow crystals. Compound 1 crystalized in the monoclinic space group P21/c and was found to have a distorted octahedral geometry. The P–W–N angle was slightly more acute than expected, presumably due to an unusual N–H⋯π interaction. The solid state structure of cis-[W(CO)4(PPh3)(pip)] (1) is described with an P–W–N angle slightly more acute than expected, presumably due to an N–H⋯π interaction.
