Binuclear ligands possessing two discrete multidentate N-heterocyclic podand coordination sites connected by a flexible propylene spacer and a rigid m-xylene spacer were synthesized. Treatment of the binuclear ligands with Ni(Oac)2 afforded the bimetallic nickel(II) complexes with two discrete nickel centers. The single-crystal X-ray structure determination of the bimetallic nickel(II) complex with a propylene spacer revealed a little distorted square planar geometry at each nickel center.
合成了拥有两个独立多齿N-杂环泡丹配位位点的双核配体,这两个配位位点通过灵活的丙烯间隔和刚性的m-二甲苯间隔连接。用Ni(Oac)2处理双核配体得到带有两个独立镍中心的双金属镍(II)配合物。对带有丙烯间隔的双金属镍(II)配合物进行单晶X射线结构测定显示,每个镍中心呈现出略微畸变的方平面几何结构。
