Sumario:The title compound, Pb(2)Mn(3)(HPO(4))(2)(PO(4))(2), was synthesized by a hydro­thermal method. All atoms are in general positions except for one Mn atom which is located on an inversion center. The framework of the structure is built up from PO(4) tetra­hedra and two types of MnO(6) octa­hedra, one almost ideal and the other very distorted with one very long Mn—O bond [2.610 (4) Å compared an average of 2.161 Å for the other bonds]. The centrosymetric octa­hedron is linked to two distorted MnO(6) octa­hedra by an edge common, forming infinite zigzag Mn(3)O(14) chains running along the b axis. Adjacent chains are linked by PO(4) and PO(3)(OH) tetra­hedra through vertices or by edge sharing, forming sheets perpendicular to [100]. The Pb(2+) cations are sandwiched between the layers and ensure the cohesion of the crystal structure. O—H⋯O hydrogen bonding between the layers is also observed.
