Poly[tris­(μ-benzene-1,4-dicarboxylato)bis­(dipyrido[3,2-a:2′,3′-c]phenazine)trimanganese(II)]

In the title compound, [Mn(3)(C(8)H(4)O(4))(3)(C(14)H(8)N(4))(2)](n), one Mn atom is located on an inversion centre and is six-coordinated by four carboxyl­ate O atoms from different benzene-1,4-dicarboxyl­ate (1,4-bdc) ligands and two phenanthrene N atoms from a dipyrido[3,2-a:2′,3′-c]phenazine ligand. The other Mn atom is also six-coordinate, binding to six carboxyl­ate O atoms from different 1,4-bdc ligands. The dicarboxyl­ate groups chelate and bridge the two Mn atoms and a symmetry-related Mn atom to form a trimanganese unit. Bridging of the trinuclear Mn(II) clusters leads to a two-dimensional structure.
