Abstract

Reaction of the five-co-ordinate [Ni(NP3)X]X complexes [NP3= tris(2-diphenylphosphinoethyl)amine; X = Cl, Br, I] with MX2 salts (M = Fe, Co, Ni, Zn) gives complexes of general formula NiM(NP3)X4. Spectrophotometric, conductometric, and far-i.r. data suggest for these complexes a binuclear non-ionic structure consisting of a square-planar ‘core’ with a NiNP2X chromophore, and a pseudo-tetrahedral ‘core’ with a MPX3 chromophore. The analogous nickel–manganese complexes undergo selective oxidation with formation of a phosphine oxide, probably bonded to MnII.
由镍(II)和其他三维二价离子与三脚架配体形成的双核混合金属配合物
五配位[Ni(NP3)X]X配合物[NP3=三(2-二苯基膦乙基)胺的反应X = Cl, Br, I]与MX2盐(M = Fe, Co, Ni, Zn)配合得到通式NiM(NP3)X4。分光光度法、电导法和远红外法。数据表明,这些配合物的双核非离子结构由一个带有NiNP2X生色团的方形平面“核”和一个带有MPX3生色团的伪四面体“核”组成。类似的镍锰配合物经过选择性氧化形成氧化膦,可能与MnII结合。
