title: catena-Poly[[(1,10-phenanthroline)manganese(II)]-μ(3)-5-methyl-isophthalato].
abstract: In the title coupound, [Mn(C(9)H(6)O(4))(C(12)H(8)N(2))](n), the Mn(II) ion is coordinated by two N atoms [Mn-N = 2.273 (3) and 2.305 (2) Å] from a 1,10-phenanthroline ligand and four O atoms [Mn-O = 2.112 (2)-2.343 (3) Å] from three 5-methyl-isophthalate (mip) ligands in a distorted octa-hedral geometry. Each mip dianion acts as a tetra-dentate ligand connecting three Mn ions. The crystal packing exhibits π-π inter-actions [3.599 (2)-3.755 (2) Å] between the centroids of the six-membered rings of neighbouring 1,10-phenanthroline ligands.
