Synthesis and solid-state structural characterization of N,N′-dicyclohexyldithiooxamide complexes of HgX2 (X = SCN or Cl)

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...
