✦ Synopsis

On the basis of quantum-chemical calculation of methane, methylaluminum and methylindium, it is shown that essentially the non-divided 2s -electron pair of the carbon atom has the ability to take part in specific intermolecular interaction. Thermodynamic 2 analysis of structural changes in solutions of the Al(CH ) -In(CH ) , Al(CH ) -In(C H ) systems substantiated the formation 3 3 3 3 3 3 2 5 3

of solvate structures in which four types of interaction were involved. It is shown that specific intermolecular interaction with the participation of pentacoordinated carbon atom is approximately twice higher than the energy of the hydrogen bond in liquid ammonia.
