Abstract: The title complex, [Mn₂(C₈H₇O₃)₄(C₁₂H₈N₂)₂]·0.5CH₃OH, is a carboxylate-bridged dinuclear Mn^II 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 - 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-HO hydrogen bonds connect the dinuclear units into a three-dimensional supramolecular framework.
