The synthesis and characterization of bis-mercaptoethanediazaheptane cadmium(II) is reported and compared to the analogous zinc complex. Of significance is the dimeric form of the [Zn(N(2)S(2))](2) complex achieves penta-coordination about zinc through a bridging thiolate whereas cadmium engages two thiolate as S-bridges resulting in hexa-coordination about cadmium within a coordination polymer...

Tris(2-pyridylthio)methane ([Tptm]H) has been employed to synthesize a series of cadmium carbatrane compounds that feature an [N3C] coordination environment. Specifically, [Tptm]H reacts with Cd[N(SiMe3)2]2 to afford [Tptm]CdN(SiMe3)2, which thereby provides access to other derivatives. For example, [Tptm]CdN(SiMe3)2 reacts with (i) CO2 to form {[Tptm]Cd(μ-NCO)}2 and (ii) Me3SiOH and Ph3SiOH to...

The asymmetric unit of the title compound, [Cd(2)Cl(2)(NCS)(2)(C(15)H(15)NO(2))(2)](n), contains the Schiff base 2-[(4-methyl-phenyl-imino)meth-yl]-6-methoxy-phenol (HL) ligand, one thio-cyanate and one chloride ligand coordinated to a cadmium centre. The cadmium centers are linked to each other via two thio-cyanate and two chloride bridges alternately, resulting in centrosymmetric zigzag chain...

The centrosymmetric title compound, [Cd(C(9)H(9)BrNO(2))(2)], was obtained by the reaction of 5-bromo-salicyl-aldehyde, 2-amino-ethanol and cadmium nitrate in ethanol. The Cd atom, located on an inversion centre, is hexa-coordinated by two Schiff base ligands in an octa-hedral coordination through the phenolate O atom, the imine N atom and the hy-droxy O atoms. In the crystal, mol-ecules are li...
