    Coordination and bonding of Co(II) ions at cationic sites in zeolites of ZSM-5, FER and MOR structures were investigated by x-ray absorption and UV-Vis and FTIR spectroscopy. Three types of Co ion sites are present in each of these structures (Vis spectroscopy of Co ions). Accomodation of the Co ions in these sites is followed by perturbation of framework T-O bonds (FTIR) possessing similar Co-O distance close to 2 A (EXAFS) in all these sites.
