摘要

The title compound, [Zn3(C14H11Br2N2O)4](ClO4)2·2CH3CN, crystallizes as a symmetrical trinuclear cation with all three metal atoms being located on a twofold rotation axis. It contains a tetrahedral ZnII atom that bridges two six-coordinate ZnII atoms. The complex contains N- and O-donor atoms of four tridentate 2,4-dibromo-6-{[2-(pyridin-2-yl)ethyl]iminomethyl}phenolate ligands. The ratio of ZnII atoms to ligands is 3:4. The two terminal ZnII cations adopt distorted octahedral geometries and the central ZnII cation adopts a distorted tetrahedral geometry. In the cation there are π–π interactions between the dibromophenyl rings, as well as halogen-bonding interactions between the dibromophenyl rings in the cation, which stabilize its conformation. In addition, there are C—H⋯O interactions between the anions and both the cations and solvent molecules as well as C—H⋯N interactions between the cation and solvent molecules. These interspecies interactions link the cations, anions and solvent molecules into a complex three-dimensional array
