Comparison of σ/ π-hole aerogen-bonding interactions based on C2H4···NgOX2 (Ng = Kr, Xe; X = F, Cl, Br) complexes

The geometric structure, energy properties, and electronic properties of the aerogen-bonding interaction formed by C 2 H 4 and NgOX 2 (Ng = Kr, Xe; X = F, Cl, Br) have been studied at the B2PLYP-D3(BJ)/ aug-cc-pVTZ (PP) level. Two kinds of aerogen-bonding interactions were observed among the title s...

Zusammenfassung:The geometric structure, energy properties, and electronic properties of the aerogen-bonding interaction formed by C 2 H 4 and NgOX 2 (Ng = Kr, Xe; X = F, Cl, Br) have been studied at the B2PLYP-D3(BJ)/ aug-cc-pVTZ (PP) level. Two kinds of aerogen-bonding interactions were observed among the title systems: the σ-hole and the π-hole complexes. The σ-hole aerogen-bonding complex has a binding energy in the range of − 6.29 ~  − 8.17 kcal/mol, which is the most stable. The binding energies of C 2 H 4 ···NgOX 2 increased as X = F
