title: Poly[tris-(μ-benzene-1,4-dicarboxylato)bis-(dipyrido[3,2-a:2',3'-c]phenazine)trimanganese(II)].
abstract: 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 carboxyl-ate O atoms from different benzene-1,4-dicarboxyl-ate (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 carboxyl-ate O atoms from different 1,4-bdc ligands. The dicarboxyl-ate 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.
