摘要
The ternary complexes X- center dot 1 center dot YF (1 = triazine, X = Cl, Br and I, Y = H, Cl, Br, I, PH2 and AsH2) have been investigated by MP2 calculations to understand the noncovalently electron-withdrawing effects on anion-arene interactions. The results indicate that in binary complexes (1 center dot X-), both weak sigma-type and anion-pi complexes can be formed for Cl- and Br-, but only anion-pi complex can be formed for I-. Moreover, the hydrogen-bonding complex is the global minimum for all three halides in binary complexes. However, in ternary complexes, anion-pi complex become unstable and only sigma complex can retain in many cases for Cl- and Br-. Anion-pi complex keeps stable only when YF = HF. In contrast with binary complexes, s complex become the global minimum for Cl- and Br- in ternary complexes. These changes in binding mode and strength are consistent with the results of covalently electron-withdrawing effects. However, in contrast with the covalently electron-withdrawing substituents, Cl- and Br- can attack the aromatic carbon atom to form a strong s complex when the noncovalently electron-withdrawing effect is induced by halogen bonding. The binding behavior for I- is different from that for Cl- and Br- in two aspects. First, the anion-pi complex for I- can also keep stable when the noncovalent interaction is halogen bonding. Second, the anion-pi complex for I- is the global minimum when it can retain as a stable structure.
