New mixed-ligand heterometallic coordination polymers of the type [MM'(Et(2)dtc)(2)(bzta)2], [MM'(XCN)(2)(Et(2)dtc)(2)] [Cu2Hg(SCN)(2)(bzta)(2)] and [CuAg(SCN)(bzta)] [M = Ni(II) or Cu(II); M' = Ni(II), Zn(II), Cd(II), Hg(II), Pb(II) or 2Ag(I); X=S or Se; bzta(-) = benzothiazole-2-thiolate (C6H4NSCS-); Et(2)dtc(-) = diethyldithiocarbamate {(C2H5)(2)NCS2-}] have been prepared by reacting the above mixed-ligands and heterometal salts in a single-pot reaction and characterized by spectroscopic methods (IR, FT-Raman, Electronic and EPR), magnetic susceptibility, and conductivity measurements. All the complexes exhibit sigma(rt) close to 10(-8) ohm(-1) cm(-1) and are insulators ill the 303-393 K temperature range. The sigma(rt) of I-2-doped products of some of the complexes are increased in 10-10(2) order of magnitude and show the behaviour Of semiconductors over the given temperature range.
