Аннотация:In binary complexes of methane and ethane with HCl and LiCl, the effect of monomers orientation on C...H-Cl/Li-Cl bonding was studied using the MP2/aug-cc-pVTZ method. Calculations predict the formation of ethane complexes with “parallel” and “perpendicular” orientation of HCl/LiCl molecules relative to the C–C covalent bond line of ethane. Decomposition of binding energy into components shows that in H-bonded complexes exchange repulsion and dispersion prevail over electrostatics and charge transfer. Stabilization of complexes with a Li-bond is mainly determined by the polarization component. Due to dispersion interactions, the perpendicular configuration of ethane complexes becomes more stable than the linear configuration.
