Tetra-kis(μ-phenoxy-acetato-κO:O')bis-[(1,10-phenanthroline-κN,N')manganese(II)] methanol hemisolvate

The title complex, [Mn(2)(C(8)H(7)O(3))(4)(C(12)H(8)N(2))(2)]·0.5CH(3)OH, is a carboxyl-ate-bridged dinuclear Mn(II) complex with four phenoxy-acetate ions and two 1,10-phenanthroline mol-ecules as ligands. Each of the four phenoxy-acetate anions bridges the pair of Mn atoms. The asymmetric unit is completed by a half-occupancy methanol solvent mol-ecule. Face-to-face π-π stacking inter-actions between the aromatic rings of 1,10-phenanthroline molecules belonging to adjacent Mn(2) complexes, with an inter-planar separation of circa 3.4 Å, and weak C-H⋯O hydrogen bonds connect the dinuclear units into a three-dimensional supra-molecular framework.
