摘要：

Reaction of zinc(II) chloride with the ligand N, N'- {2,4-(di-2-pyridylamino)-1,3,5-triazin-6-yl}-1,4,10,13-tetraoxa-7,16- diazacyclooctadecane (oxodendtriz) in acetonitrile/methanol results in the formation the tetranuclear complex [Zn-4( oxodendtriz)Cl-8]( CH3CN)(2)(H2O)(1.5). Notably, its crystal structure reveals unique pi-interactions with the first experimental evidence of electronrich/ electron-poor molecule pairing, which is corroborated by computational studies. In addition, infinite helical water chains with both right- and left-handed configurations are present in the crystal lattice.
