In the title compound, [Zr(C10H15)2(C14H12NO)(CN)], the Zr(IV) atom is coordinated by two penta-methyl-cyclo-penta-dienyl ligands, the amidate ligand via the N and O atoms, and an additional C N ligand. The four-membered metallacycle is nearly planar (r.m.s. deviation = 0.008 Å). In the crystal, the mol-ecules are connected into centrosymmetric dimers via pairs of N-H⋯N hydrogen bonds.

The title compound, [Cd(C(5)H(10)NO(2)S(2))(2)(C(10)H(8)N(2))], features a trigonal-prismatic coordination geometry for the Cd(II) ion, based on an N(2)S(4) donor set defined by two chelating dithio-carbamate ligands and a 2,2'-bipyridyl ligand. In the crystal, extensive O-H⋯O hydrogen bonding results in the formation of 12-membered {⋯HO}(6) synthons and one-dimensional supra-molecular chains w...
