摘要：
A new zinc phosphate of the formula, [NH2(CH2)(3)NH3][Zn-4(PO4)(2)(HPO4)(2)], has been synthesized hydrothermally starting from a zinc amine complex. It crystallizes in the monoclinic space group C2/c; a = 17.279(1), b = 5.193(1), c = 20.115(1) Angstrom, beta = 92.6(1)degrees; V = 1803.1(2) Angstrom(3); Z = 4; D-calc = 2.05 g cm(-3); mu (MoK alpha) = 5.62 mm(-1). The final R, and wR(2) = 0.037, 0.093 obtained for 136 observed data [I>2 sigma(I)]. The structure consists of macroanionic sheets of interconnected ZnO4 and PO4 tetrahedra in the ab plane. The sheets are held together by hydrogen bond interactions with the organic structure-directing amine, forming alternate inorganic-organic layers in this material. Hydrogen bond interactions between the inorganic layers, via the terminal -OH group, leads to the formation of pseudo one-dimensional channels. (C) 1999 Elsevier Science Ltd. All rights reserved.
