Abstract The σ-hole interaction (type I), counterintuitive II) and type Ш noncovalent system formed between three heterocyclic compounds (C 4 H O, C 5 N 2 ) AtX (X = F, Cl Br) have been investigated employing the MP2/aug-cc-pVTZ. For N-AtX -AtX complexes, calculated energy decreases according to sequence I > II Ш. O-AtX same AtX, of complexes O. while for O . SAPT analysis shows that electrostatic are predominantly attraction typeⅠcomplexes Ⅲ interactions mainly dispersion energy. Ⅱ induction, term playing important in total attractive interaction. NBO also employed.
