The intrinsic dynamic and static natures of the E⋯E′ interactions at the 1,8-positions of 1-(MeE)–8-(MeE′)C10H6 [1a–1f (E ≠ E′) and 1g–1j (E = E′)] were elucidated with QTAIM-DFA, after structural determination of 1-(PhE)–8-(PhE′)C10H6 (3a–3f), where (E, E′: x) = (O, S: a), (O, Se: b), (O, Te: c), (S, Se: d), (S, Te: e), (Se, Te: f), (O, O: g), (S, S: h), (Se, Se: i) and (Te, Te: j) (χE ≥ χE′).

在1-(MeE)–8-(MeE')C 10 H 6 [ 1a–1f(E≠E')和1g–在结构确定1-(PhE)-8-(PhE')C 10 H 6(3a-3f)之后,用QTAIM-DFA阐明了1j(E = E')] ,其中(E,E':x) =(O,S:a),(O,Se:b),(O,Te:c),(S,Se:d),(S,Te:e),(Se,Te:f),( O,O:g),(S,S:h),(Se,Se:i)和(Te,Te:j)(χ Ë ≥ χ E' )。虽然AB结构确认了图3a,图3b和3D-3F,其由n个的p(E)⋯σ*(E'-C博士)相互作用,所述结构为BB为图3c,其中所述E-C - [R / E'– CR(R = Ph)键垂直于A中的萘平面,并将其放置在B中的平面上。虽然AB结构通过在p确定的(E)-π(PH)缀合,所述BB结构是由晶体堆积的效果。这未检测到具有n p(E')⋯σ*(E–C
