2,4'-BITHIAZOLE AND BIS(2,4'-BITHIAZOLE)BIS(DIMETHYL SULFOXIDE)COPPER(II) DIPERCHLORATE

The synthesis and crystal structure of 2,4'-bithiazole, C6H4N2S2 (I), and its copper complex [Cu(C6H4N2-S-2)(2)(C2H6OS)(2)](ClO4)(2) (II) are presented. The bithiazole molecules are planar in both compounds. The 2,4'-bithiazole (I) molecule is located on a symmetry center and the structure was solved by the introduction of disorder between the S atom and its neighbour S/C2, which caused a small deviation in the S-C and C-C bond distances. Other bond distances and angles are as expected. In the copper complex (II), the Cu atom is hexacoordinated and the 2,4'-bithiazole moiety again presents statistical disorder giving the ligand a local mirror symmetry.
