Tetrakis(μ-phenoxyacetato-κ2O:O′)bis[(1,10-phenanthroline-κ2N,N′)manganese(II)] methanol hemisolvate

Abstract

The title complex, [Mn2(C8H7O3)4(C12H8N2)2]·0.5CH3OH, is a carboxylate-bridged dinuclear MnII complex with four phenoxyacetate ions and two 1,10-phenanthroline molecules as ligands. Each of the four phenoxyacetate anions bridges the pair of Mn atoms. The asymmetric unit is completed by a half-occupancy methanol solvent molecule. Face-to-face π–π stacking interactions between the aromatic rings of 1,10-phenanthroline molecules belonging to adjacent Mn2 complexes, with an interplanar separation of circa 3.4 Å, and weak C—H...O hydrogen bonds connect the dinuclear units into a three-dimensional supramolecular framework.
