ABSTRACT
The structure of the polymeric title compound, [CuCl(CH(4)N(2)S)(2)](n), has been redetermined to modern standards of precision with anisotropic refinement and location of the H atoms. The previous structure report [Spofford & Amma (1970 â¶). Acta Cryst. B26, 1474-1483] is generally confirmed to higher precision [typical Cu-S bond length s.u. values = 0.005 (old) and 0.001â
Å (new)]. The asymmetric unit contains two formula units, with both Cu(I) atoms coordinated by one terminal S atom and two bridging S atoms of thio-urea ligands. This connectivity leads to polymeric [100] chains in the crystal. If very long contacts to nearby chloride ions [2.8687â
(9) and 3.1394â
(12)â
Å] are considered to be bonding, then very distorted CuS(3)Cl tetra-hedral coordination polyhedra arise. The crystal structure is consolidated by weak intra- and inter-chain N-Hâ¯S and N-Hâ¯Cl hydrogen bonds.
