Estimation of the Stability of Clusters with the Aid of the Theory of the Electron Density Functional

The likely usefulness of the application of simple versions of the theory of the electron density functional to the study of the energy characteristics of cluster compounds is discussed. Three types of cluster compounds are considered: clusters of elements as an intermediate form between a molecule and a solid, organometallic clusters, and organoelemental compounds of the nido-cluster type. The question of the variation of the bond energy in homoatomic clusters as a function of their size and steric structure is analysed.
