trans-Bis(dimethyl sulfoxide-κO)bis-(3-nitro-benzo-hydroxamato-κ2O,O′)zinc(II)

摘要

Single crystals of the title complex, [Zn(C 7 H 5 N 2 O 4 ) 2 (C 2 H 6 OS) 2 ] or [Zn(NBZH) 2 (DMSO) 2 ], were isolated from a dimethyl sulfoxide (DMSO) solution containing [Zn(NBZH) 2 ]·2H 2 O (NBZH = 3-nitro-benzo-hydroxamate anion). The asymmetric unit comprises of one O , O ′-chelating NBZH anion, one O-bound DMSO ligand and one zinc(II) cation localized on an inversion centre. The three-dimensional crystal packing includes N—H?O and C—H?O hydrogen bonding, as well as O?H and H?H contacts identified by Hirshfeld isosurface analysis.
