英文摘要 | We theoretically study chalcogen bonds involving SF2 and SFH, each paired with various unsaturated hydrocarbons ethyne, ethene, 1,3-butadiene, and benzene. The binding energies are calculated at theory level MP2, M06-2X-D3 and CCSD(T)/CBS, respectively. Geometry structure, binding energies, interaction type and strength are studied comparatively. SFH engages in a stronger chalcogen bond than does SF2 for all systems, which indicates that SFH is a stronger electron acceptor than SF2. Two kinds of energetic effects are observed, SF2 center dot center dot center dot cis-butadiene complex contain the strongest chalcogen bond among all the SF2 center dot center dot center dot pi complexes, which is attributed to the energetic effect of two S center dot center dot center dot pi interactions. For SFH center dot center dot center dot pi complexes, the strongest interaction is formed between SFH and C6H6, which can be explained by the synergistic effects of the S center dot center dot center dot pi and S-H center dot center dot center dot pi interaction. The largest charge transfer arises from the occupied C-C bonding orbital to the sigma*(S-F) antibonding orbital. The quantity is considerably larger for SFH than for SF2. (C) 2019 Elsevier B.V.
