Abstract: | Chemical preparation, crystallographic data, thermal behavior, and IR studies are given for two cyclotriphosphates MnNa 4 (P 3 O 9 ) 2 ;4H 2 O and its anhydrous form MnNa 4 (P O 9 ) 2 . MnNa 4 (P 3 O 9 ) 2 ;4H 2 O, isotypic of CuK 4 (P 3 O 9 ) 2 ;4H 2 O, is monoclinic P2 1 /a with the following unit-cell dimensions: a = 8.536(2) Å, b = 14.309(3) Å, c = 8.508(2) Å, g = 96.452(2); and Z = 2. MnNa 4 (P 3 O 9 ) 2 , isotypic of CaNa 4 (P 3 O 9 ) 2 , is monoclinic C2/c with the following unit-cell dimensions: a = 13.198(2) Å, b = 8.241(1) Å, c = 14.228(2) Å, g = 95.045(1); and Z = 4. The thermal behavior has been investigated and interpreted by comparison with IR absorption spectrometry and x-ray diffraction experiments. |
