摘要：
Unprecedented anion?π interactions are revealed for the electron-poor triazine rings in [L2(CuCl)3][CuCl4]Cl (L = hexakis(pyridin-2-yl)-[1,3,5]-triazine-2,4,6-triamin), where both the chloride ion and a Cl atom of [CuCl4]2- are located ∼3.15 Å above the ring centroids, in excellent agreement with theoretical predictions for a Cl-⋯triazine complex. This confirms the importance of attractive anion?π interactions for the supramolecular assembly of complexes with π-electron-deficient heteroaromatics. Copyright © 2004 American Chemical Society.
