Synthesis and Crystal Structure of Mononuclear Nickel Ethanedithiolate Complex with 1,2-bis(diphenylphosphino)ethane

Abstract

The title complex (dppe)Ni(edt) [dppe = 1,2-bis(diphenylphosphino)ethane, edt = ethanedithiolate] was prepared by treatment of (dppe)NiCl₂ with HSCH₂CH₂SH in the presence of Et₃N in CH₂Cl₂ at room temperature and structurally characterized by ¹H NMR, ³¹P{¹H} NMR, ¹³C{¹H} NMR and ESI-MS spectroscopy. In addition, the molecular structure was determined by single crystal X-ray diffraction analysis. The title complex consists of a distorted square planar NiP₂S₂ core coordinated by dppe and edt. The van der Waals’ interactions stabilize the solid state in the crystal packing.
