Hexa-μ ₂-benzoato-bis­(2,2′-bipyrid­yl)trimanganese(II) monohydrate

Abstract

The complex molecule of the title compound, [Mn ₃(C ₇H ₅O ₂) ₆(C ₁₀H ₈N ₂) ₂]·H ₂O, contains a linear array of divalent manganese ions. The central Mn ^II atom, which is located on a crystallographic inversion center, is coordinated octa­hedrally by six benzoate O atoms. The two terminal Mn ^II ions are six-coordinated by four benzoate O atoms and two N atoms of 2,2′-bipyridyl. The central Mn ^II atom and the terminal Mn ^II ions are bridged by four benzoate ligands in a bidentate fashion, whereas the other two carboxyl­ate ligands form bridges through one O atom only and chelate the terminal Mn ^II atom. The mol­ecules pack together via van der Waals attractions and C—H⋯O hydrogen bonds.
