[μ-1,3-Bis(3,5-dimethyl-1H-pyrazol-1-yl-κN2)propan-2-olato-κ2O:O]bis[(ethanol-κO)zinc(II)] bis(perchlorate)

Abstract

In the centrosymmetric dinuclear title complex, [Zn2(C13H19N4O)2(C2H5OH)2](ClO4)2, the ZnII atom is in a distorted trigonal-bipyramidal coordination geometry. The equatorial plane is constructed by one N atom and one O atom from two 1,3-bis(3,5-dimethylpyrazol-1-yl)propan-2-olate (bppo) ligands and one O atom from an ethanol molecule. One N atom and one O atom from the two bppo ligands occupy the axial positions. Intermolecular O—H...O hydrogen bonds between the ethanol molecules and perchlorate anions, and O...π interactions between the perchlorate anions and pyrazole rings [O...centroid distances = 3.494 (3) and 3.413 (3) Å], lead to a chain structure along [010].
