[?-1,3-Bis(3,5-dimethyl-1H-pyrazol-1-yl-?N)propan-2-olato-?O:O]bis-[(ethanol-?O)zinc(II)] bis-(perchlorate).

ABSTRACT: In the centrosymmetric dinuclear title complex, [Zn(2)(C(13)H(19)N(4)O)(2)(C(2)H(5)OH)(2)](ClO(4))(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-dimethyl-pyrazol-1-yl)propan-2-olate (bppo) ligands and one O atom from an ethanol mol-ecule. One N atom and one O atom from the two bppo ligands occupy the axial positions. Inter-molecular O-H?O hydrogen bonds between the ethanol mol-ecules and perchlorate anions, and O?? inter-actions 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].
