Synthesis and structural characterization of a novel tin (II) oxyphosphate, [NH4+]2[Sn3O(PO4)2]2–·H2O, containing one-dimensional chains constructed from tin phosphate cages

Abstract

The hydrothermal synthesis and single crystal structure of a novel tin(ii) oxyphosphate, [NH 4 + ] 2 [Sn 3 O(PO 4 ) 2 ] 2– H 2 O, made from the networking of distorted square-pyramidal SnO 4 and tetrahedral PO 4 moieties, is presented. Crystal data: a=7.240(1), b=19.552(3), c=8.438(1) Å; V=1194.5(3) Å 3 ; space group Cmc2 1 (no. 36) and Z=2. The structure, dominated by the presence of a large number of three-coordinated oxygen atoms and Sn}}n1O}}n1Sn linkages, creating an oxy-phosphate unit, consists of capped three-membered rings (cages) connected to each other via phosphate groups forming infinite one-dimensional chains. These chains are related to each other via multipoint hydrogen bonding involving the protonated ammonium and water molecules.
