Group 11 Complexes with Imidazoline‐2‐thione or Selone Derivatives

Abstract

Abstract The reactions of the organodichalcogenone ligands Bbit[1,1′‐(butane‐1,4‐diyl)bis(3‐methylimidazoline‐2‐thione)],Mbis [1,1′‐methylenebis(3‐methylimidazoline‐2‐selone)], Ebis [1,1′‐(ethane‐1,2‐diyl)bis(3‐methylimidazoline‐2‐selone)] and Pbis [1,1′‐(pentane1,5‐diyl)bis(3‐methylimidazoline‐2‐selone)] with gold(I/III), silver(I) and copper(I) have been studied by elemental analysis, multinuclear ( 1 H, 13 C, 19 F, 31 P and 77 Se) NMR spectroscopy and for several products obtained the molecular structures were also established by single‐crystal X‐ray diffraction analysis. In most cases the organodichalcogenone coordinates to two metallic fragments as a bidentate bridging ligand but the ligand Mbis coordinates to silver(I) in an unprecedented tetradentate bridging‐chelate mode.
