Abstract: | The electronic structure and geometrical structure of NO-3, BF-4, ClO-4 and FSO-3 anions are studied by means of the ab initio molecular orbital method. According to the results obtained, the central atoms of these anions are all positively charged and the surrounding atoms negatively charged. The bonding nature of ClO-4 and FSO-3 is similar to that of XF-6 (X = P, As and Sb) previously studied, and has a coordination-like character. However, BF-4 and NO-3 show a covalent-like character. The ion radii of these anions are determined from the total density contour maps obtained by the calculation. |
