Abstract
The crystal structures of N(3)-methylthiosemicarbazide, bis{N(3)-methylthio semicarbazide}copper(II) chloride and bis(hexamethyleneiminylthiosemicarbaz ide)copper(II) chloride are reported. Two forms of N(3)-methylthiosemicarba zide exist, which have different modes of intermolecular hydrogen bonding. Both copper(II) complexes are coordinated by the hydrazinic nitrogen and th ione sulfur of the thiosemicarbazides in a cis arrangement. Further, for bo th complexes each of the NH hydrogens of the coordinated thiosemicarbazides interact with one of the chloride anions. (C) 2000 Elsevier Science B.V. A ll rights reserved.
