摘要：

kA new cyclotriphosphate trihydrate of strontium and ammonium, SrNH4P3O9. 3H(2)O, was obtained as single crystals by the metathesis reaction of Boulle. Its thermal behavior and crystal structure are given. SrNH4P3O9. 3H(2)O crystallizes in the orthorhombic system, Pnma, with the following unit cell parameters: a = 9.126 (1)Angstrom, b = 8.157 (1)Angstrom, c = 15.256 (2)Angstrom and Z = 4. Its crystal structure has been determined and refined down to R = 0.037, using 6263 independent reflections. The thermal behavior has been investigated and interpreted by IR absorption and X-ray diffraction experiments. (C) 2000 Editions scientifiques et medicales Elsevier SAS. All rights reserved.
