Abstract
Abstract The reactions of 5-(4′-dimethylaminobenzylidene)rhodanine (HDABRd) and 5-(2′-thiophenomethylene)rhodanine (HTRd) with methyl- and phenylmercury(II) acetate yielded [HgR(DABRd)] and [HgR(TRd)] (R=Me, Ph), respectively. These complexes were characterized and studied by IR and NMR (1H, 13C{1H} and 199Hg) spectroscopy, and X-ray diffractometry, respectively. In both structures the rhodanine ligand coordinates to the mercury atom via its N(3) atom, and HgC(13) and HgN(3) are almost collinear. The mercury atom also forms intra- and intermolecular secondary bonds. In particular, an Hg⋯S bond associates the [HgPh(DABRd)] molecules in zig-zag chains parallel to the b axis, and an Hg⋯O bond links the [HgMe(TRd)] molecules in centrosymmetric dimers.
