Bis(diphenylphosphino)ethane nickel polychloridophenylthiolate complexes: synthesis and characterization

Abstract

Reactions of (dppe)NiCl2 (dppe = 1,2-bis(diphenylphosphino)ethane) with chlorido-substituted phenyl thiolates (RClS−) produced the corresponding nickel thiolate complexes (dppe)Ni(SRCl)2 (RCl = 3,5-C6H3Cl2 (1), C6Cl5 (2)) in high isolated yields. Complexes 1 and 2 were characterized by spectroscopic techniques such as (UV–Vis, IR, 1H-, 31P{1H}-, 13C{1H}-NMR) as well as elemental analysis. The molecular structures of complexes 1 and 2, determined by X-ray diffraction measurements, have a cis square planar geometry.
