Crystal structure and magnetic properties of NaCuII[(CuII3O)(PO4)2Cl]

Anion-Centered Tetrahedra in Inorganic Compounds

“…These chains have been described as basic structure entities in a number of compounds. Recently, Jin et al reported on the structure and properties of NaCu + [(Cu 2+ 3 O)­(PO 4 ) 2 Cl] and compared configurations of the [O 2 Cu 6 ] 8+ chains in different compounds (Figure ). In allochalcoselite, Cu + [PbCu 2+ 5 O 2 ]­(SeO 3 ) 2 Cl 5 , , one of the nonshared Cu atoms in every second tetrahedron is replaced by the Pb 2+ cation so that the chain has the [O 2 Cu 5 Pb] 8+ composition (Figure ).…”

“…Comparison of the linear [O 2 Cu 6 ] chain of (OCu 4 ) tetrahedra in the structures of (a) NaCu­[(Cu 3 O)­(PO 4 ) 2 Cl], (b) NaCu I [(Cu II 3 O)­(PO 4 )­Cl], and (c) Cu II 3 O­(MoO 4 ). Reprinted with permission from ref . Copyright 2012 Elsevier B. V.…”

“…Recent papers − testify increasing attention to the inorganic compounds consisting of anion-centered tetrahedra, and the goal of this review is to present a comprehensive account of the theory and review of experimental data accumulated on these materials over the last 50 years.…”

Mineral-like Synthetic Compounds Stabilized under Hydrothermal Conditions: X-ray Diffraction Study and Comparative Crystal Chemistry

“…The channels contents differ in the amount of sodium cations, as well as the atomic positions of the interstitial ions. Notably, similar salt inclusions, often found in host-guest structures, are also observed in oxo-cuprates synthesized through halide flux methods, such as Na 2 Cu 3 OCu(PO 4 ) 2 Cl [25] and NaCu 3 OCu(PO 4 ) 2 Cl [27]. However, hydrothermal synthesis techniques are also suitable for the preparation of these compounds, as shown in [22,28].…”

“…Other structurally related phases, i.e., NaCu 3 OCu(PO 4 ) 2 Cl [27] and Cu 1,5 Cu 3 O(PO 4 ) 2 Cl [26], only contain divalent copper cations. All discussed structures are formed from the same ribbon fragments of Cu 2+ -centered polyhedra, interconnected through anionic tetrahedra.…”
