Crystal structure of [Co(NH3)(5)NO3](NO3)(PF6) center dot 1.5H(2)O and the vibrational bands of its normal and (NO3)-N-15-enriched cation
Résumé
The crystal structure of [Co(NH3)(5)NO3](NO3)(PF6) center dot 1.5 H2O was studied by X-ray diffraction methods in order to obtain the unknown molecular structure of the [Co(NH3)(5)NO3](2+) cation . The substance crystallizes in the monoclinic system, space group C2/m, with a = 18.6231(6) angstrom, b = 7.8757(3) angstrom, c = 9.6434(3) angstrom and beta = 95.484(2)degrees. An infrared and Raman study of the bromide salt was also performed and the spectra interpreted with the aid of (NO3)-N-14/(NO3)-N-15 isotopic replacement and quantum chemistry calculations.
