An extended 1D network formed by complementary hydrogen bonding between Pt(IV)-complexed tetrazoles

The first metal complex containing the N-1-ligated tetrazole, viz., trans- [PtCl4(5-Me-4H-tz-kappa N-1)(2)] (1), has been prepared by the reaction between trans-[PtCl4(EtCN)(2)] and 5-methyltetrazole and characterized by elemental analyses, FAB(+)-MS, IR, and H-1, C-13{H-1}, Pt-195 NMR spectroscopies and also by X-ray diffraction. In the solid state, 1 displays a novel type of complementary hydrogen-bonding between the -NH- and -N=moieties of the heterocycles from the neighbouring molecules, thus forming an extended ID network.
