摘要

The FT IR and FT Raman spectra of Co(en)(3)Al3P4O16 . 3H(2)O (compound I) and [NH4](3)[Co(NH3)(6)](3)[Al-2 (PO4)(4)](2) . 2H(2)O (compound II) are recorded and analysed based on the vibrations of Co(en)(3)(3+), Co(NH3)(6)(3+), NH4+, Al-O-P, PO3, PO2 and H2O. The observed splitting of bands indicate that the site symmetry and correlation field effects are appreciable in both the compounds. In compound I, the overtone of CH2 deformation Fermi resonates with its symmetric stretching vibration. The NH4 ion in compound II is not free to rotate in the crystalline lattice. Hydrogen bonding of different groups is also discussed. (C) 2000 Elsevier Science B.V. All rights reserved. [References: 39]
