Synthesis and characterization of binuclear manganese carbonyl complex of 1,4-bis(2-(2′-hydroxyphenyl)benzimidazol-1-yl)benzene and dimethylaminopyridine

Abstract

A neutral heteroleptic binuclear complex fac-[{Mn(CO)3(Py′)}2(L)] with Mn⋅⋅⋅Mn separation of ~13.5 Å was synthesized using Mn2(CO)10, 1,4-bis(2-(2′-hydroxyphenyl)benzimidazol-1-yl)benzene (H2-L), 4-dimethylaminopyridine (Py′), and trimethylamine N-oxide (Me3NO) via one-pot approach. Complex 1 adopts a helical structure in the solid-state.
