摘要：
Complexes of anions with several six-membered inorganic rings with more or less aromatic character have been optimized at the RI-MP2/aug-cc-pVDZ level of theory. The rings studied are hexazine (N-6), boroxine (B3O3H3), borazine (B3N3H6), 1,3,5,2,4,6-triazatriborinine (B3N3) ring, and borthiin (B3S3H3). The anion-pi complexes are energetically favorable and the interaction has been characterized by means of the Bader's theory of 'atoms-in-molecules' and partitioning the energy using the SAPT method. Experimental evidence of the importance of this interaction in some inorganic rings has been obtained from the Cambridge Structural Database. (C) 2012 Elsevier B. V. All rights reserved.
