HETEROBIMETALLIC COMPLEXES OF GOLD AND MERCURY - SYNTHESES AND CHARACTERIZATIONS OF HGII(CH2P(S)PH2)2(AUICL)2 AND HGIIAUI(CH2P(S)PH2)2AUIIICL4

The trinuclear compound HgII(CH2P(S)Ph2)2(AuICl)2 (2) was synthesized by the reaction of HgII-(CH2P(S)Ph2)2 (1) with 2 equiv of Au(THT)Cl (THT = tetrahydrothiophene) in a CH2C12 solution. Oxidation of 2 by 1 equiv of C6H5IC12 yielded the mixed-valence trinuclear compound HgIIAuIH(CH2P(S)Ph2)2AuIIICl4 (3). The crystal structures of 2 and 3 were determined by single-crystal X-ray diffraction analyses. 2 and 3 have one-dimensional chain structures in the solid.
