Four zinc/platinum(II) heterobimetallic coordination polymers with dithiocarboxylate-functionalized carboxylate (DTCC) ligands were prepared by different synthetic approaches and characterized by elemental analyses, IR and NMR (H-1, C-13, and Pt-195) spectroscopy, thermal analyses coupled with mass spectrometry (TG/DTA/MS), and single-crystal and powder X-ray diffraction studies. Sequential syntheses via the carboxylic acid substituted platinum dithiocarbamates and zinc acetate revealed crystalline products in good to excellent yields. One-pot preparations from potassium DTCC salts, K2PtCl4, and ZnCl2 led to comparable products, thus demonstrating the high selectivity of the two donor groups toward platinum(II) and zinc. [SSC-N(Me)CH2COO](2-) and [SSC-N(CH2COO)(CH2COOH)](2), DTCC ligands derived from sarcosine and iminodiacetic acid, respectively, were found to form planar zigzag chains with zinc and platinum(II) ions, while the use of the L-proline-derived ligand [SSC-NC4H7COO](2-) results in a helical structure. In the case of [SSC-N(CH2COO)(2)](3)(-), two-dimensional arrays are formed. All compounds are thermally stable up to 240-400 degrees C under nitrogen.
