摘要：

The compounds [Ni-II(iitp)(2)] 1 (iitp=2-iminoisopropyl-thiophenolate), [Ni-2(II)(imptp)(2)]. 2CH(3)OH 2, a dinuclear compound with an Ni-Ni distance of 276 pm, and [PPh(4)].[Ni-II(imptp)(SCN)] 3 (imptp=2-(2-iminopentane-4-on)-thiophenolate) have been prepared by the reaction of nickel(II)-acetate-tetrahydrate with 2-iminoisopropyl-thiophenole and 2-(2-iminopentane-4-on)-thiophenole in methanol, respectively. They have been characterized by single-crystal X-ray structure analysis and other physical methods. The redox behaviour of 1-3 has been studied in detail (chemically as well as by cyclovoltammetry and ESR spectroscopy). Particularly interesting are the electronic properties of 1 and its reduction with NaBH4 and the following reaction of the product with O-2 The complexes are model compounds for some Ni-containing enzymes. For details of the crystal structure determination see ''Inhaltsubersicht''.
