چکیده انگلیسی
Chemical preparation, X-ray characterization, IR spectroscopy and thermal analysis of a new cyclotriphosphate: (C7H10NO)3P3O9·4H2O abbreviated as OACTP, are reported. This mixed organo-mineral compound crystallizes in the monoclinic system with P21/n space group, the unit cell dimensions are: a = 6.605(3) Å, b = 26.166(3) Å, c = 18.671(8) Å, β = 91.95(3)°, Z = 4 and V = 3255(2) Å3. The structure was solved using a direct method and refined to a reliability R-factor of 0.043 using 3931 independent reflections (I > 2σI). Atomic arrangement exhibits infinite (P3O9·2H2O)n3n− chains connected by organic cations. The thermal behavior and the IR spectroscopic studies of this new compound are discussed.
