Synthesis and structure of a layered zinc phosphate–acetate, [C5H10NH2]2[Zn(ZnO2CCH3)(PO4)(HPO4)]

Abstract

The solution-mediated synthesis and single crystal structure of an inorganic–organic hybrid solid [C₅H₁₀NH₂]₂[Zn(ZnO₂CCH₃)(PO₄)(HPO₄)], I, is presented. The structure of I is built up from a network of ZnO₄, ZnO₃(OAc) and PO₃(OH) tetrahedral units, connected through their vertices, forming macroanionic two-dimensional sheets with four- and eight-membered apertures. The acetate groups are perpendicular to the plane of the layers and project from the Zn center into the inter-lamellar region. The charge compensating organic cations, piperidinium, are also located in between the layers. The connectivity within the layers shows close similarity to the three-dimensional zinc phosphate with gismondine topology.
