A highly rigid ditopic ligand has been prepared which consists of a terpy fragment connected in the back to a phen nucleus via a 1,4-phenylene linker. The chemical structure of the presently reported ligand is such that the coordination axes of the two chelates are orthogonal to one another. The reaction of this phen–terpy conjugate with zinc(II) surprisingly affords in good yield a dinuclear complex in spite of the tension of the generated structure, whereas coordination of copper(II) centres to the two-chelate ligand enables the formation of the trinuclear complex also.
已经制备了一种高度刚性的双位配体,该配体由一个terpy片段通过1,4-苯基连接器与苯核连接在一起。所报道的配体的化学结构使得两个螯合物的配位轴彼此正交。尽管生成的结构存在张力,这种苯–terpy共轭物与锌(II)的反应意外地以良好的产率形成二核配合物,而铜(II)中心与该双螯合配体的配位也能形成三核配合物。
