Synthesis and structural characterization of a layered tin(II) phosphate, [Sn-2(PO4)(2)](2-)[C2N2H10](2+)center dot H2O

摘要

A new layered tin(II) phosphate [Sn-2(PO4)(2)](2-)[C2N2H10](2+). H2O was synthesized by hydrothermal technique. It crystallizes in monoclinic space group P2(1)/c (No. 14) with lattice parameters a 9.4112(1) Angstrom; b = 8.5998(1) Angstrom; c = 15.9921(2) Angstrom; beta = 100.009(1)degrees; V= 1274.61(2); Z = 4; R = 2.06%; R-w = 2.17%. The structure consists of inorganic layers, comprising a network of strictly alternating SnO3 and PO4 moieties and held together by strong hydrogen bonding between the layers. Protonated ethylenediamine and water molecules are trapped between the layers. (C) 1998 Academic Press. [References: 32]
