Dicaesium magnesium bis(dihydrogen phosphate(V)) dihydrate

  • The title compound, Cs2Mg(H2P2O7)2·2H2O, is isostructural with the related known isoformular phosphates. The crystal framework consists of corner-sharing MgO6 and H2P2O7 polyhedra, leading to tunnels parallel to the b-axis direction in which Cs+ ions are located. The H2P2O7 unit shows a bent eclipsed conformation. The Mg2+ ion lies on an inversion center. The water molecules form hydrogen bonds to O atoms of two different dihydrogenphosphate ions, which are further hydrogen bonded to symmetry-equivalent dihydrogenphosphate ions. Key indicators: single-crystal X-ray study; T = 173 K; mean σ(P–O) = 0.006 Å; R factor = 0.048; wR factor = 0.125; data-to-parameter ratio = 12.3.
