摘要
A zinc phosphate compound with composition (ZnPO4)(4)(H2PO4)(2)(C4N2H14)(2) was synthesized by the hydrothermal reaction of zinc oxide and phosphoric acid in the presence of 1,4-diaminebutane. The crystal structure was solved from powder data and exhibits triclinic symmetry with a = 8.6590(3) Angstrom, b = 10.3467(3) Angstrom, c = 8.3910(3) Angstrom, alpha = 102.180(2)degrees, beta = 93.676(2)(degrees) and gamma = 88.203(2)degrees. The new organo-zincophosphate has sheets built from saw-type four member ring ladders, where ZnO4 and PO4 tetrahedrons alternate. Additional phosphate groups project into the interlayer voids where the protonated amine resides. (C) 2001 Elsevier Science B.V. All rights reserved.
