Crystal structure of tetra-kis-(?₂-(E)-2,4-di-bromo-6-{[2-(pyridin-2-yl)eth-yl]imino-meth-yl}phen-olato)trizinc bis-(perchlorate) aceto-nitrile disolvate.

ABSTRACT: 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 tetra-hedral Zn^II atom that bridges two six-coordinate Zn^II atoms. The complex contains N- and O-donor atoms of four tridentate 2,4-di-bromo-6-{[2-(pyridin-2-yl)eth-yl]imino-meth-yl}phenolate ligands. The ratio of Zn^II atoms to ligands is 3:4. The two terminal Zn^II cations adopt distorted octa-hedral geometries and the central Zn^II cation adopts a distorted tetra-hedral geometry. In the cation there are ?-? inter-actions between the di-bromo-phenyl rings, as well as halogen-bonding inter-actions between the di-bromo-phenyl rings in the cation, which stabilize its conformation. In addition, there are C-H?O inter-actions between the anions and both the cations and solvent mol-ecules as well as C-H?N inter-actions between the cation and solvent mol-ecules. These inter-species inter-actions link the cations, anions and solvent mol-ecules into a complex three-dimensional array.
