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

In the centrosymmetric dinuclear title complex, [Zn-2(C13H19N4O)(2)(C2H5OH)(2)](ClO4)(2), the Zn-II 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 center dot center dot center dot O hydrogen bonds between the ethanol molecules and perchlorate anions, and O center dot center dot center dot pi interactions between the perchlorate anions and pyrazole rings [O center dot center dot center dot centroid distances = 3.494 (3) and 3.413 (3) angstrom], lead to a chain structure along [010].
