Abstract
Single crystal structure of HGdP2O7·3H2O has been solved, for the first time, using 2344 X-ray reflections with a final R value: 0.029. This salt crystallizes in the triclinic system; the space group is P1, with Z = 2 and the following unit-cell dimensions: a=6.4585(4) b=6.976(1) c=9.803(1) Å α=98.48(1) β=99.439(8) γ=88.388(9)° V=430.93(9) Å3 The atomic arrangement of HGdP2O7·3H2O is built by pairs of HP2O73- anions interconnected by strong hydrogen bonds and located around the inversion center at (0, 0, 1/2). The cohesion between these entities is provided by GdO8 polyhedra.
