The tris(1,2,3-triazol-4-yl)methane framework offers a highly versatile architecture for ligand design, yet the coordination chemistry of this class of ligand remains largely unexplored. We report here the synthesis and characterisation of the homoleptic complexes [M(ttzm)2](PF6)2 (ttzm = tris(1-benzyl-1,2,3-triazol-4-yl)-p-anisolylmethane; M = Fe (Fe), Ru (Ru), Os (Os)). Initial attempts to prepare
tris(1,2,3-triazol-4-yl)methane 框架为配体设计提供了一种高度通用的结构,但这类配体的配位化学在很大程度上仍未得到探索。我们在此报告了同配络合物 [M(ttzm) 2 ](PF 6 ) 2 (ttzm = tris(1-benzyl-1,2,3-triazol-4-yl)- p -anisolylmethane; M = Fe ( Fe )、Ru ( Ru )、Os ( Os ))。通过 [Ru( p -cymene)Cl 2 ] 2和 ttzm 的反应制备Ru的初步尝试也导致了杂配络合物 [Ru( p -cymene)(ttzm)](PF6 ) 2.[Ru( p -cymene)(ttzm)](PF 6 ) 2、[Fe(ttzm) 2 ] 2+ (作为其BPh 4 -盐)和Os的结构通过X射线衍射求解。由于 ttzm 配体的 ansiole 和三唑环之间的空间相互作用,含有均配Fe(
