Abstract
A new Ni(II) complex, {[NiL(THF)]2(μ-OAc)2Ni} (H2L = 4,4'-dibromo-2,2'-[(ethylene)dioxybis(nitrilomethylidyne)]diphenol), has been synthesized and characterized structurally. The results show that the complex consists of three Ni(II) atoms, two tetradentate (μ-L)2- units, two coordinated μ-acetate ions which coordinate to three Ni(II) atoms in μNi-O-C-O-Ni mode and two coordinated THF molecules. All the hexa-coordinated Ni(II) atoms of the complex have a distorted octahedral geometry. The crystal packing of the complex shows that a notable feature of this structure resides in the formation of an infinite 2D supramolecular networks through intermolecular C-H···O hydrogen-bonding and C-H···p interactions.
