| Abstract: | Pseudoelement Compounds. VIII. [1]. On the Coordination Behaviour of Potential Ambidentate Aryl-cyanamidosulfonate Ligands Aryl-cyanamidosulfonates form with metal(II) ions (Co, Ni, Cu, Zn, Cd, Hg, Pd, Pt) complexes of the types MX2, [MX2L2], [MX2L4] and [MX4]2?. The ionic, potentially ambidentate ligand [RSO2NCN]? is monodentately coordinated via the terminal nitrogen atom and bidentately in a bridging function through the nitrile group end-on (equatorial) and one of the two sulfonyl oxygen atoms (axial). The new compounds are characterized by means of ir and uv-vis spectroscopy. In the case of [Ni(NCNSO2C6H4Me-4)2(py)4] the molecular and crystal structure was determined. |
