摘要：
The reactions of iron(III) dibutyl and di-iso-butyl dithiocarbamates [Fe(S2CNR2)(3)] (R = C4H9, iso-C4H9) with anions [AuCl4](-) in 2 M HCl are studied. The result of heterogeneous reactions of gold(III) chemisorption binding from a solution is the formation of gold(III)-iron(III) heteropolynuclear complexes of the ionic type. The crystal and supramolecular structures of polymer complexes ([Au{S2CN(C4H9)(2)}(2)][FeCl4]) (n) (I) and ([Au{S2CN(iso-C4H9)(2)}(2)][FeCl4]) (n) (II) are determined by X-ray diffraction analysis (CIF files CCDC 1407704 (I) and 1407802 (II)). The structure of complex I contains two centrosymmetrical structurally nonequivalent complex cations [AuS{2CN(C4H9)(2)}(2)](+) (A and B) and complex anion [FeCl4](-). Structure II is formed by three isomeric complex cations [Au{S2CN(iso-C4H9)(2)}(2)](+) (D, D', and D) and two anions [FeCl4](-) related as conformers. The isomeric cations are involved in the formation of linear (aEuro broken vertical bar DaEuro broken vertical bar D'aEuro broken vertical bar) (n) (in I) or zigzag (aEuro broken vertical bar DaEuro broken vertical bar D'aEuro broken vertical bar DaEuro broken vertical bar DaEuro broken vertical bar) (n) (in II) polymer chains due to pairs of weak secondary interactions Au center dot center dot center dot S. The thermal behavior of the complexes is studied by simultaneous thermal analysis. Thermal destruction includes the thermolysis of the dithiocarbamate moiety of the complexes and anions [FeCl4](-) with the reduction of gold(III), release of FeCl3, and partial formation of Fe2O3. The final thermolysis products are metallic gold and Fe2O3.
