Title: | Effective core potential ab initio calculations on main group heptoxides and large silicate systems | Authors: | Ribeiro-Claro, P. J. A. Amado, A. M. |
Keywords: | Heptoxides; Silicate; Zeolites; Molecular structures; Effective core potentials; B3LYP method | Issue Date: | 2000 | Citation: | Journal of Molecular Structure: THEOCHEM. 528:1-3 (2000) 19-28 | Abstract: | The ab initio molecular structures for several main group heptoxides (X2O7n-, n=0,2,4) are calculated using effective core potentials at the HF and DFT (B3LYP) levels. Particular attention is given to the X-O-X bond angle, as this structural parameter is a key feature for the study of both heptoxides and larger derivatives, such as polysilicate systems. The extent of the p-d interactions, which was found to be the main factor governing the magnitude of the X-O-X angle in transition metal heptoxides, does not play a significant role in the main group analogues. | URI: | https://hdl.handle.net/10316/5242 | DOI: | 10.1016/S0166-1280(99)00400-5 | Rights: | openAccess |
