Growth and structural characterization of [ZnL(DMSO)]

A novel mononuclear zinc(II) complex ZnL(DMSO)] (1) with chelating bisoxime ligand 4,4′‐dinitro‐2,2′‐ethylenedioxybis(nitrilomethylidyne)]diphenol (H₂L) was synthesized and structurally characterized by X‐ray crystallography. The complex crystallizes in the triclinic system, space group P‐1, with unit cell parameters a = 8.9730(16), b = 11.9080(18), c = 20.701(2) Å, α = 103.893(3), β = 101.975(3), γ = 90.029(2) and Z = 4. The Zinc(II) ion is five‐coordinated by four N₂O₂ donor atoms of L^2‐ and one oxygen atom from DMSO molecule. Interestingly, the unit of cell contains two crystallographically independent but chemically identical mononuclear complexes. (© 2007 WILEY ‐VCH Verlag GmbH & Co. KGaA, Weinheim)
