Abstract: | The interaction of binuclear cadmium dialkyldithiocarbamates Cd2(S2CNR2)4] with solutions of AuCl3 in 2M HCl gives polynuclear gold(III) complexes (Au(S2CNR2)2]AuCl4])
n
, where R = C4H9 (I) and R2 = (CH2)5 (II). The structures of the synthesized compounds solved by X-ray diffraction analysis are char-acterized by a complicated organization
at the supramolecular level. The structures are based on polymer chains (I) and layers (II) involving isomeric cations Au(S2CNR2)2]+ and anions AuCl4]−. The thermal behavior of the synthesized complexes is studied by simultaneous thermal analysis including thermogravimetry
and differential scanning calorimetry. The final product of the thermal transformations of the studied complexes is shown
to be reduced metallic gold. |
