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

A neutral heteroleptic binuclear complex fac-[{Mn(CO)(3)(Py')}(2)(L)] with Mn center dot center dot center dot Mn separation of similar to 13.5 angstrom was synthesized using Mn-2(CO)(10), 1,4-bis(2-(2'-hydroxyphenyl)benzimidazol-1-yl)benzene (H-2-L), 4-dimethylaminopyridine (Py'), and trimethylamine N-oxide (Me3NO) via one-pot approach. Complex 1 adopts a helical structure in the solid-state. (C) 2021 Elsevier B.V. All rights reserved.
