摘要：
The title compound, [Zn-2(C21H25N2)(2)(OH)(2)], is a binuclear zinc complex formed by two bidentate beta-diketiminate (nacnac) ligands and two mu-hydroxide O atoms, bridging two mononuclear units into a centrosymmetric dimeric unit. Each Zn2+ cation is coordinated by two N-donor atoms from the nacnac ligand and two O-donor atoms of hydroxide anions to give a distorted tetrahedral coordination environment. The Zn-O bond lengths are 1.9643 (13) and 2.0022 (14) angstrom, and the two Zn-N bond lengths are 1.9696 (14) and 1.9823 (14) angstrom. The distance between the two Zn2+ cations in the dimer is 2.9420 (4) angstrom. Although hydroxide groups are present in the complex, no classical hydrogen-bonding interations are observed because of the bulky beta-diketiminate ligands.
