Title: The molten hydrated flux synthesis of a novel open-framework copper borophosphate and its structural relation with the precursors

Abstract

A novel copper borophosphate, Cu{sub 2}(H{sub 2}O)[BP{sub 2}O{sub 7}(OH)], has been synthesized by the molten hydrated flux method. Its crystal structure (Orthorhombic, Pbca, a=8.234 Å, b=9.655 Å, c=17.805 Å, V=1415.485 Å{sup 3}, Z=8) can be regarded as the condensation of alternately edge- and corner-shared copper pyramidal chains and borophosphate chains formed via vertex-sharing PO{sub 4} and BO{sub 3}(OH) tetrahedra. Magnetic measurements indicate that antiferromagnetic interactions exist in the title compound. Due to the special reaction medium created by the molten hydrated flux method, a possible structural correlation between final solids and raw materials has been discovered even though no ordered structural fragments exist in the latter. - Graphical: Structure comparison of Cu(NO{sub 3}){sub 2}·3H{sub 2}O, Cu(NO{sub 3}){sub 2}·H{sub 2}O and Cu{sub 2}(H{sub 2}O)[BP{sub 2}O{sub 7}(OH)], showing the structural evolution of CuO{sub 5} pyramids in the synthetic process. - Highlights: • A novel copper borophosphate has been synthesized by the molten hydrated flux method. • Magnetic measurements show its antiferromagnetism at low temperature. • A structural relation between the precursor and the final solid is discovered.
