Syntheses and structural characterization of Ni(II) chelates of a new series of symmetric and unsymmetric tetradentate linear ligands are described. Preparative routes involve either the direct reaction between a metal complex and arene diazonium diazonium salts or a simple metal incorporation into the independently synthesized ligands.

描述了一系列新的对称和不对称四齿线性配体的Ni(II)螯合物的合成和结构表征。制备途径涉及金属络合物和芳烃重氮鎓重氮盐之间的直接反应或简单的金属掺入独立合成的配体中。最近对4,9-二甲基-5,8-二氮杂十二烷基-4,8-二烯-2,11-二酮-3,10-二(4'-甲基苯基)肼基tonickel(II)的X射线结构测定显示Ni(II)周围的几何形状非常接近正方形平面。由于在相邻氮原子上大量芳族基团的布置而导致的预期畸变通过它们在与平面相反的方向上的投影而得以最小化。配合物的PMP,IR和电子光谱数据与该结构完全一致。
