Investigation of complexes of zinc(II) and cadmium(II) di-n-butyldithiocarbamates with 2,2 '-bipyridyl

A new mixed-ligand complex, Cd(S2CN(C4H9)(2))(2)(2,2'-Bipy), was synthesize d. A polycrystal X-ray diffraction analysis was performed (DRON-3M and DRON -UM1 diffractometers, CuKalpha radiation, Ni filter) and the crystal struct ure was determined [Enraf-Nonius CAD-4 automatic diffractometer, MoKalpha r adiation, 2440 nonzero independent reflections, 153 refined structural para meters, R is 0.11 for 1 > 2 sigma(1)]. Crystal data for C28H44CdN4S4: a = 2 8.716(4), b = 6.848(6), c = 17.188(2) Angstrom, space group Pcca, V = 3380. 2(7) Angstrom(3), Z = 4, M = 679.42, d(calc) = 1.335 g/cm(3). The structure consists of monomeric molecules in which the cadmium atom has a distorted octahedral environment. The polycrystal diffraction analysis revealed that the complex is isostructural with the defined complex Zn(S2CN(C4H9)2)2(2,2' -Bipy). A crystal-chemical search on metal dialkyldithiocarbamates in the C ambridge Structural Database was accomplished and isostructural pairs of Zn and Cd metal complexes were found.
