Synthesis and characterization of 2-(2-benzimidazolyl)-6-methylpyridine Cu(I)Fe(II) heterodinuclear complex
摘要
Abstract
A Cu(I)Fe(II) heterometallic dinuclear complex [Cu(Hbmp)(dppf)](ClO4) (1) was synthesized by using 1,1'-bis(diphenylphosphino)ferrocene (dppf), 2-(2-benzimidazolyl)-6-methyl pyridine (Hbmp) and [Cu(CH3CN)4] (ClO4) as raw materials. As revealed by single-crystal X-ray diffraction, compound 1 is a Cu(I)Fe(II) heterodinuclear complex, in which the Cu(I) ion adopts a four-coordinate mode and connects with two N and two P atoms to form a distorted tetrahedral configuration, while the Fe(II) ion is sandwiched between two cyclopentadienyl moieties to generate a staggered sandwich biscuit geometry. Complex 1 has a weak low-energy broad absorption in the 355~460 nm region, which is assigned to metal-to-ligand charge-transfer (Cu(I)→Hbmp, MLCT) transition, mixed with some ligand-to-ligand charge-transfer (dppf→Hbmp, LLCT) transition.关键词
