Abstract:
N,N′-Dicyclohexyldithiooxamide (H2L) reacted with HgX2 (X = SCN or Cl) to form the novel mercury mixed-ligand complexes [Hg(H2L)(SCN)2] 1, [HgCl2(H2L)] 2 and [{HgCl2(H2L)}2]·EtOH 3. The crystal and molecular structures of 1 and 3 have been determined. Crystals of 1 are monoclinic, space group P21/n (no. 14), with a = 11.318(1), b = 17.727(2), c = 11.536(2) Å, β = 109.08(2)°and Z = 4. Crystals of 3 are monoclinic, space group P21 (no. 4), with a = 8.563(1), b = 21.414(3), c = 11.649(2) Å, β = 103.58(2)° and Z = 2. The structures were each refined by a full-matrix least-squares procedure to R1 = 0.031 for 2218 reflections with F2 ≥ 2.0σ(F2) for 1 and R1 = 0.047 (2374 reflections) for 3. Complex 1 is mononuclear with HgS4 units linked by short intermolecular S⋯S interactions. Complex 3 is a binuclear zwitterionic system with one S,S′-chelating H2L ligand bonded to a mercury atom and a second ligand acting in an unusual conformation as a S,S′-bidentate bridging group between the ionic species HgS2Cl+ and HgCl3-. The two mercury atoms are separated at a non-interacting distance. The infrared spectra of the complexes in the range 650-200 cm-1 are discussed in the light of the known structures.
