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