Triphosphine and diphosphine ligands with backbones designed to facilitate metal–arene interactions were employed to support multinuclear Ni complexes. Di- and trinuclear metal complexes supported by a triphosphinecontaining a triarylbenzene linker display diverse metal–arene binding modes. Multinuclear Ni halide complexes were isolated with strongly interacting metal centers bound to opposite faces
采用旨在促进金属-芳烃相互作用的主链的三膦和二膦配体来支撑多核镍配合物。由含有三芳基苯连接基的三膦支持的二核和三核金属配合物显示出多种金属-芳烃结合模式。多核镍卤化物络合物被分离出来,其强相互作用的金属中心与配位芳烃的相对面结合。在二碘化三镍配合物2与四羰基铁酸二钠反应时,分离出共面三角镍(0)配合物4 。 Ni 0 3簇基序还可以由对三联苯二膦支持,其中末端一氧化碳配体取代第三膦供体。所有多核配合物都具有强金属-芳烃相互作用,证明了芳烃作为小簇的多功能配体设计元素的用途。
