Three Zn(II) adducts of N-alkyl-N-phenyl dithiocarbamate with 2,2'-bipyridine have been synthesized and characterized by elemental analysis and spectroscopic techniques. The compounds are formulated as [Zn(mpdtc)(2)bpy] (1), [Zn(epdtc)(2)bpy] (2). and [Zn(bpdtc)(2)bpy] (3) (where m = methyl, e = ethyl, b = butyl; p = phenyl and bpy = 2,2'-bipyridine). The single crystal X-ray structures of compounds (1) and (2) are also reported. It revealed that compound (1) exists as a five coordinate trigonal bipyramidal structures in which one dithiocarbamate acts as a chelating ligand and the other occupying the apical position acts as a monodentate ligand, while compound (2) exists as six coordinate octahedral species. Each of the two compounds has four molecules in the unit cell with the uncoordinated S atom in complex involved in a weak C-H center dot center dot center dot S interaction. The thermal decomposition profiles of the compounds are also reported. (C) 2010 Elsevier B.V. All rights reserved.
