The use of 2-pyridinealdoxime (paoH)/N,N'-donor ligand (L-L) "blend" in cobalt chemistry has afforded two cationic mononuclear cobalt(III) complexes of the general type Co(pao)(2)(L-L), where L-L = 1,10-phenanthroline (phen) and 2,2'-bipyridine (bpy). The CoCl(2)/paoH/L-L (1 : 2 : 1) reaction system in MeOH gives complexes [Co(III)(pao)(2)(phen)]Cl.2H(2)O (1.2H(2)O) and [Co(III)(pao)(2)(bpy)]Cl.1.5MeOH (2.1.5MeOH). The structures of the complexes were determined by single-crystal X-ray crystallography. The Co(III) ions are six-coordinate, surrounded by three bidentate chelating ligands, that is, two pao(-) and one phen or bpy. The deprotonated oxygen atom of the pao(-) ligand remains uncoordinated and participates in hydrogen bonding with the solvate molecules. IR data of the complexes are discussed in terms of the nature of bonding and the known structures.
使用 2-吡啶醛肟（paoH）/N，N'-供体配体（L-L）“混合物”在钴化学中提供了两种阳离子单核钴（III）配合物，其通式为[Co（pao）（2）（L-L）]（+），其中 L-L = 1,10-菲咯啉（phen）和 2,2'-联吡啶（bpy）。MeOH 中的 CoCl2 /paoH/L-L（1：2：1）反应体系生成配合物[Co（III）（pao）（2）（phen）]Cl.2H2O（1.2H2O）和[Co（III）（pao）（2）（bpy）]Cl.1.5MeOH（2.1.5MeOH）。通过单晶 X 射线晶体学确定了配合物的结构。Co（III）离子是六配位的，被三个双齿螯合配体包围，即两个 pao（-）和一个 phen 或 bpy。pao（-）配体的去质子氧原子保持未配位，并与溶剂分子参与氢键。配合物的 IR 数据根据键的性质和已知结构进行了讨论。
