摘要: A MP2/6-311+ +G(d,p) study of NCX (X = F, Cl, Br) has shown that it is possible to attach an electrophile (H+, Be2+) the positive halogen X surface NCX. The stability and properties model halogen-bonded π-hole carbon-bonded NCX/H2O complexes were found be significantly affected by H+ or Be2+ cationic attachment at N atom. are destabilised binding N, while attached proton enhances in bonded dimers. For Be2+, unusual complex was obtained with NCF subunit, whereas containing Cl Br interaction.
