Crystal structure of tetra­kis­(μ(2)-(E)-2,4-di­bromo-6-{[2-(pyridin-2-yl)eth­yl]imino­meth­yl}phen­olato)trizinc bis­(perchlorate) aceto­nitrile disolvate

The title compound, [Zn(3)(C(14)H(11)Br(2)N(2)O)(4)](ClO(4))(2)·2CH(3)CN, crystallizes as a symmetrical trinuclear cation with all three metal atoms being located on a twofold rotation axis. It contains a tetra­hedral Zn(II) atom that bridges two six-coordinate Zn(II) 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 Zn(II) atoms to ligands is 3:4. The two terminal Zn(II) cations adopt distorted octa­hedral geometries and the central Zn(II) 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
