摘要：

Chemical preparation, X-ray characterization, IR spectroscopy and thermal analysis of a new cyclotriphosphate: (C7H10NO)(3)-P3O9 center dot 4H(2)O abbreviated as OACTP, are reported. This mixed organo-mineral compound crystallizes in the monoclinic system with P2(1)/n space group, the unit cell dimensions are: a = 6.605(3) angstrom, b = 26.166(3) angstrom, c = 18.671(8) angstrom, beta = 91.95(3)degrees, Z = 4 and V = 3255(2) angstrom(3). The structure was solved using a direct method and refined to a reliability R-factor of 0.043 using 3931 independent reflections (I > 2 sigma I). Atomic arrangement exhibits infinite (P3O9 center dot 2H(2)O)(n)(3n-) chains connected by organic cations. The thermal behavior and the IR spectroscopic studies of this new compound are discussed.
