catena-Polybis(ethane-1,2-diammonium) manganese(II)-di--phosphato-4O:O': a one-dimensional manganese phosphate
Abstract
The title compound, {(C2H10N2)2Mn(PO4)2}n, contains anionic square-twisted chains of formula Mn(PO4)24- constructed from corner-sharing four-membered rings of alternating MnO4 and PO4 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.
