Abstract
Bis(N,N-dimethylthiocarbamoyl) sulfide (Tetramethylthiuram monosulfide) reacts with copper(II) halides (halide = Cl and Br) to yield 3,5-bis(N,N-dialkyliminio)-1,2,4-trithiolane trihalocuprate(I) and the neutral halogeno(bis(N,N-dimethylthiocarbamoyl) sulfido)copper(I) complex. The proposed structure for the trihalocuprate(I) compounds is supported mostly by infrared studies. The copper(I) adducts may also be prepared by straightforward reaction of copper(I) halides and the ligand, and single-crystal x-ray studies show a wide diversity of structural variations. All molecules consist of basic S2CuX units. The Cl derivative (1) is an S-bridged dimer (C6H14ClCuN2OS3, monoclinic, P21/c (No. 14), Z = 4, a = 9.525(8) A, b = 13.022(10) A, c = 10.835(7) A), while the Br analogue (2) features a polymeric network of S2CuBr units, also bridged by S atoms (C6H12BrCuN2S3, orthorhombic, P212121 (No.19), Z = 4, a = 7.043(2) A, b = 9.442(3) A, c = 17.889(4) A). The iodo compound (3) exists as a halogen-bridged dimer (C6H...
