Chloro(N-ethyl-1,3-imidazolidine-2-thione)gold(I): Spectroscopic studies and x-ray structure

Summary Chloro(N-ethyl-1,3-imidazolidine-2-thione)gold(II) crystallizes in the triclinic space group P¯I with cell dimensions:a=7.213(2)Å,b=7.857(7)Å,c=9.056(3)Å, =108.54°, =100.06(3)°, =107.27(4)° and Z=2.,The structure was refined by a least squares method to a conventional R factor of 7.3%, using 2157 reflections. The metal atom is bonded through the sulfur atom of the ligand which is consistent with the¹³C n.m.r. spectra of the complexes in d₆-acetone. The structure of the complex and coordination around metal are compared with other linear gold(I) complexes.
