Nickel(II), palladium(II), zinc(II) and copper(II) complexes of new constrained 2,2′-bidipyrrin ligands (H2BDP) with a peripheral eight-membered ring were prepared and examined with respect to coordination modes and conformation. NiII and PdII ions form mononuclear complexes with a distorted square-planar N4 coordination, which was determined for the palladium derivative by single-crystal X-ray diffraction
镍 (II)、钯 (II)、锌 (II) 和铜 (II) 配合物与外围八元环的新的受约束的 2,2'-双吡喃配体 (H2BDP) 被制备并检查了配位模式和构象。NiII 和 PdII 离子形成具有扭曲的方形平面 N4 配位的单核配合物,这是通过单晶 X 射线衍射确定的钯衍生物。ZnII 离子导致双核 M2L2 螺旋的形成,对于 CuII 离子,实现了两种配位模式。X 射线晶体学分析揭示了 CuII 和 ZnII 联二吡啉的双核螺旋的 M…M 距离短,并且两者在固态下的堆积模式各自不同。(© Wiley-VCH Verlag GmbH & Co.
