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 ( 1 H, 13 C, and 195 Pt) 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, K 2 PtCl 4 , and ZnCl 2 led to comparable products, thus demonstrating the high selectivity of the two donor groups toward platinum(II) and zinc. [SSC-N(Me)CH 2 COO] 2− and [SSC-N(CH 2 COO)-(CH 2 COOH)] 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-NC 4 H 7 COO] 2− results in a helical structure. In the case of [SSC-N(CH 2 COO) 2 ] 3− , two-dimensional arrays are formed. All compounds are thermally stable up to 240−400 °C under nitrogen.

Heterobimetallic compounds of the type M’2[Pt(L)2] (L = N-dithioato-iminodiacetate, {SSC-N(CH2COO)2}3–) containing different bivalent, oxophilic metals M’ were prepared in a straightforward manner from [Pt(H2L)2] and the respective metal acetates, M’(OAc)2...

Methyl xanthates of the type M(SSC-OMe) (M = Li-Cs) are readily formed when carbon disulfide is reacted with the corresponding alkali metal hydroxides in methanol exposed to air, or with the alkali metal methoxides in dry methanol or THF under exclusion of air. The reactions are easily monitored by 13 C NMR spectroscopy. The Na, K, Rb, and Cs salt could be isolated in high yields, while the Li salt decomposed upon attempted isolation. All compounds are readily complexed by

<br>Heterobimetallic compounds of the type M’2[Pt(L)2] (L = N-dithioato-iminodiacetate, {SSC-N(CH2COO)2}3–) containing different bivalent, oxophilic metals M’ were prepared in a straightforward manner from [Pt(H2L)2] and the respective metal acetates, M’(OAc)2 (M’ = Mg–Ba, M–Cu, Cd). X-ray structure determination revealed that the products exist as zero- (Mg), one- (Mn), two- (Fe, Co, Ni, Cd), or three-dimensional (Sr) assemblies in the solid state. As a result, the water solubilities and thermal stabilities of the products cover much wider ranges than it has been seen with M’2[M(L)2] compounds having different thiophilic metal centers (M = Ni, Pd, Pt). While most of the compounds show a typical diamagnetic (Mg–Ba, Cd) or paramagnetic (Mn, Co, Ni, Cu) behaviour at ambient temperature, for Fe2[Pt(L)2] ·4 H2O an antiferromagnetic interaction of the Fe atoms is assumed. <br>
