Coordination of the 2,6-bis(hydroxymethyl)pyridine-based oxido pincer ligands RR′pydimH2 [R = R′ = H (pydimH2); R = R′ = Me (pydipH2); R = 2-tolyl, R′ = Me (pydotH2)] towards late transition metals CoII, NiII, CuII, ZnII, PdII and PtII allows the formation of molecular species (complexes), which exhibit three main structural motifs in the solid state. The two main species are pentacoordinate [(RR′pydimH2)MCl2]
基于 2,6-双(羟甲基)吡啶的氧化钳配体 RR'pydimH2 [R = R' = H (pydimH2) 的配位;R = R' = Me (pydipH2); R = 2-tolyl, R' = Me (pydotH2)] 对晚期过渡金属 CoII、NiII、CuII、ZnII、PdII 和 PtII 允许形成分子种类(复合物),其在固态下表现出三个主要结构基序。两种主要物质是五配位 [(RR'pydimH2)MCl2] 和六配位 [(RR'pydimH2)2M]X2,它们在溶液中都很稳定,可以通过改变溶剂极性相互转化。歧化平衡[(RR'pydimH2)MCl2] [rlhar2] [(RR'pydimH2)2M]2+ + [MCl4]2– 用光谱学研究。手性配体 pydotH2 允许形成手性配合物。
