Copper(ii) chlorofluorophosphate: a new layered square-net for intercalating amines

Author affiliations

Abstract

Three copper(II) chlorofluorophosphates, synthesised in hydrofluorothermal conditions and characterised using single crystal X-ray diffraction, have been shown to adopt a new type of mixed-anion, layered structure. Identical two-dimensional, inorganic, square-nets, of the general formula [Cu4Cl(PO3(F,OH))4], exist in all three compounds. Three different cationic species, [NH4]+, [H-piperazine]+ and [H-1,4-diaminocyclohexane]+, can be incorporated between the inorganic layers and all three cations are oriented to hydrogen-bond to the anionic sheets. The [Cu4Cl(PO3(F,OH))4] layers are constructed from a new type of secondary building unit formed from four ClCuO4 square-based pyramids, connected via a μ4 bridging chloride ion, which are further linked via PO3(F,OH) tetrahedra.
