Abstract
The electronic structures of a series of mixed metallocarbohedrenes (metcars) Ti7MC12formed as a result of replacement of the titanium atom in the Ti8C12metcar by 4dtransition metal ions (M = Y, Zr, Nb, ..., Ag) are established using the ab initioelectron density functional method in the discrete-variational scheme. The dependences of electronic structure, charge distributions, and chemical bonds in the Ti7MC12metcars on the cluster symmetry (T hor T d) and position of the 4datom in a molecular cage are discussed. The electronic states of 4datoms in molecular titanium carbide (Ti8C12metcar) are compared with those in crystal titanium carbide (cubic TiC phase with rock salt structure). The effect of doping of the Ti8C12metcar with 4datoms on its reactivity is studied.
