Crystal structure of di-?-hydroxido-bis{[N,N'-bis-(2,6-di-methyl-phen-yl)pentane-2,4-diiminato(1-)]zinc}.

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

The title compound, [Zn2(C21H25N2)2(OH)2], is a binuclear zinc complex formed by two bidentate β-diketiminate (nacnac) ligands and two μ-hydroxide O atoms, bridging two mononuclear units into a centrosymmetric dimeric unit. Each Zn(2+) cation is coordinated by two N-donor atoms from the nacnac ligand and two O-donor atoms of hydroxide anions to give a distorted tetra-hedral coordination environment. The Zn-O bond lengths are 1.9643 (13) and 2.0022 (14) Å, and the two Zn-N bond lengths are 1.9696  ...[more]
