Copper Hydroxydiphosphate with a One-Dimensional Arrangement of Copper Polyhedra:  Cu₃[P₂O₆OH]₂

Abstract

A new copper hydroxydiphosphate Cu3(P2O6OH)2 was synthesized, by soft chemistry. The crystal structure was solved ab initio from X-ray powder diffraction data in the triclinic space group P. The structure is built up from [Cu3O10]infinity zigzag chains linked by P2O6(OH) groups to form a tridimensional framework. The [Cu3O10]infinity chains consist of edge-sharing polyhedra. The structure contains two sorts of copper polyhedra: one CuO6 octahedron and two CuO5 pyramids. Magnetization measurements confirm the presence of divalent copper and suggest antiferromagnetic interactions at low temperature.

Electronic properties and 1/3 magnetization plateau of the S=1/2 magnetism Cu3 (P2 O6 OH)2

“…From Table , one can find that the theoretical structure parameters, such as the CuCu bond lengths and the CuOCu angles are in good agreement with the experimental data . In addition, the optimized bond length between Cu(1) and its six O ligands has been measured and is consistent with previous experimental values . It is found that the Cu(1) is strongly elongated with two long apical CuO bonds of 2.393 Å along z axis, whereas in the basal plane, the CuO bonds ranging from 1.977Å to 1.996 Å.…”

Influence of 2‐Aminopyridine on the Formation of Molybdates under Hydrothermal Conditions

“…In the case of Mn and Zn, a Wolframite-based MMoO 4 structure is stabilized. Unlike other metal ions, copper(ii) ions tend to form polymeric chains [36][37][38] at around this pH, and these readily react with MoO 4 2-ions to give Lindgrenite (3). However, hydrothermal treatment of ammonium heptamolybdate with copper(ii) ions in the absence of 2-ampy results in ammonium-intercalated hexagonal molybdates.…”

Hydrothermal synthesis of potassium copper phosphate hydrate and ludjibaite microcrystals

“…Copper can accommodate various coordinations from tetrahedral or square to pyramidal and octahedral. Thirteen different structures of copper phosphates or hydroxyphosphates have been discovered to date [17]. It is well accepted that there is a close relationship between the morphology and their properties of inorganic materials, that is, morphologies determine their properties since the crystal shape dictates the interfacial atomic arrangement of the material [18][19][20][21][22][23].…”
