Copper Hydroxydiphosphate with a One-Dimensional Arrangement of Copper
Polyhedra: Cu3[P2O6OH]2. — The new title compound is obtained from a solution of
CuO in H3PO4 (152 °C, 24 h). Cu 3[P2O6OH]2 crystallizes in the triclinic space group P1
with Z = 1 (powder XRD). The structure contains [Cu3O10] zigzag chains which are
linked by P2O6(OH) groups to form a three-dimensional framework. The [Cu3O10]
chains are formed by edge-sharing of one CuO6 octahedron and two CuO5 tetragonal
pyramids. Magnetization measurements confirm the presence of divalent copper and
suggest antiferromagnetic interactions at low temperature. — (BAIES, R.;
