Abstract: In the title compound, [Mn(C₈H₄O₄)(C₁₉H₁₂N₄O)₂]_n or [Mn(1,4-BDC)(L)₂]_n, where 1,4-BDC is the benzene-1,4-dicarboxylate dianion and L is 4-(1H-1,3,7,8-tetraazacyclopenta[l]phenanthren-2-yl)phenol, the Mn^II atom is six-coordinated by two bidentate L and two monodentate 1,4-BDC ligands, resulting in a distorted trans-MnO₂N₄ octahedral geometry. The Mn^II atoms are bridged by the 1,4-BDC ligands, forming a single-chain polymer structure. In addition, neighboring single chains interact through [pi] - [pi] interactions, generating a two-dimensional network. Mn has site symmetry $\\overline{1}$ ; the complete 1,4-BDC unit is also built up by inversion symmetry.
