title: catena-Poly[bis(ethane-1,2-diammonium) [manganese(II)-di-mu-phosphato-kappa(4)O:O']]: a one-dimensional manganese phosphate.
abstract: The title compound, {(C(2)H(10)N(2))(2)[Mn(PO(4))(2)]}(n), contains anionic square-twisted chains of formula [Mn(PO(4))(2)](4-) constructed from corner-sharing four-membered rings of alternating MnO(4) and PO(4) units. The Mn and P atoms have distorted tetrahedral coordination and the Mn atom lies on a twofold axis. The linear manganese-phosphate chains are held together by hydrogen-bonding interactions involving the framework O atoms and the H atoms of the ethane-1,2-diammonium cations, which lie in the interchain spaces.
