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

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.
