Abstract:
In (NH4) H2 PO2 [Cmma, a = 7.515(6), b = 11.50(1), c = 3.988(4) A, Z = 41] the anion has accurately C2, , syrOmetry, with P-O 1.500 A, and a 0-P-0 angle of 115.1°. In (CH6 .N3) H2 PO 2. pnam, a= 9.561(8), b = 7.401(5) A, Z = 4] the anion occupies a site of symmetry m, with similar dimension. In both compounds a hydrogen-bond network extends throughout the crystal (N. 0 2.84 to 3.02 A) and involves all H atoms Of the cation. Structures were solved from, respectively, diffractometer data (R 0.074 for 210 reflections) and photographic data (R 0.074 for 488 reflections). The cell parameters of (N2 H6 ) (H2 P02)2 are: P2i/c, `a = 7.74(1), b = 6.44(1), c = 6.77(1) A, = 98.1(1)°.
