title: Do Organometallic CH4-Me(+p) Adducts and X4H(+) (X = P, As) Clusters Undergo Two-Electron Three-Center Interactions? Some Aspects of Discussion.
abstract: Most of the systems possessing true two-electron three-center interactions are electron deficient compounds like boron hydrids, closo-boranes, and some organic ions such as butonium cations. In this work, we perform a detailed study of the electron distribution for two different types of systems to which likewise interactions has been adjudicated: organometallic CH4-Me(+p) (p = 1, 2) adducts with Me, alkaline and earth alkaline metallic ions of Li, Na, K, Be, Mg, Ca in their stable gaseous phase and X4H(+) (X = P, As) simple clusters. For this purpose, topological analysis of the electron density decomposed into its effectively paired and unpaired contributions has been carried out looking for complex interactions.
