Tris(4,4',5,5'-tetramethyl-2,2'-biimidazole)zinc(II) dinitrate

R.-Q. Zou and Q. Xu

Abstract: A new six-coordinate monomeric Zn^II complex, [Zn(L)₃](NO₃)₂, where L is 4,4',5,5'-tetramethyl-2,2'-biimidazole (C₁₀H₁₄N₄), has been synthesized and characterized by X-ray diffraction techniques. The Zn^II atom, on a twofold axis, has a ZnN₆ distorted octahedral coordination environment. 4,4',5,5'-Tetramethyl-2,2'-biimidazole is bonded as a chelating ligand through its unprotonated N atoms. These discrete monomeric units possesses excellent hydrogen-bonding sites which further self-assemble into a three-dimensional supramolecular architecture through intermolecular N-HO and C-HO hydrogen bonds.
