Abstract: A reaction of a ligand 3,3´-(1,4-butanediyldinitrilo)bis(2-butanone)dioxime (BnH2) and CuCl yield green [Cu(H2dmg)Cl(μ-Cl)]2,1. The dimethylglyoxime (H2dmg) and CuIIions in 1 were in situ produced during the course of reaction and formed doubly chloro-bridged Cu(II) dimers. The geometry around copper ion is distorted square pyramidal. The weak intermolecular hydrogen bonds are observed in 1 giving 1D structure. The existence of two O–O distances of O2–O1= 2.922 Ǻ and O4–O3= 2.910 Ǻ indicates that these weak intermolecular hydrogen bonds are not equivalent. Hence doublet of the O-H stretching at 3302 and 3216 cm-1 are observed. |
