✦ Synopsis

The bis(cyclopropylammonium)dihydrogenodiphosphate monohydrate is a new diphosphate associated with the organic molecule C3HsNH2. We report the chemical preparation and the crystal structure of this organic cation diphosphate. (C3HsNH3)2H2P207.H20 is orthorhombic (S.G. : P21212t), with Z = 4 and the following unit-cell parameters : a = 4.828(1) A, b = 11.011(1) A, c = 25.645(2) A. The P207 groups and 1-/20 water molecules form a succession of bidimensional layers perpendicular to the c axis. The organic cations ensure the three-dimensional cohesion by NH---O hydrogen bonds.
