REACTION BETWEEN CUCL2 AND 2-S-METHYL-5,5-DIMETHYLIMIDAZOLINE-4-THIONE - X-RAY CRYSTAL-STRUCTURE OF S(4)(2-S-METHYL-5,5-DIMETHYLIMIDAZOLINE-4-THIONE)) COPPER(I)

catena-Chloro(mu-N(1),S(4) (2-S-methyl-5,5-dimethylimidazoline-4-thion e)) copper(I) was prepared and structurally characterized. The structu re exhibits linear polymeric chains disposed parallelly to the b axis. The structure of each chain consists of copper(I) ions coordinated in a planar trigonal geometry by the N(1) and S(4) atoms of two differen t ligand molecules and one chloride. The ligand acts as an N(1), S(4) bidentate molecule and the orientation of the imidazoline rings is det ermined by a hydrogen bond between the MI of each ring and the coordin ated chloride. The quite strong interaction between the thioether sulp hur atom of one chain, S(2), and the copper(I) of the next chain [2.89 8(2) Angstrom] is significant in the structure.
