• C-H center dot center dot center dot pi interaction

Complex [Cu-4(HL)(4)]center dot DMF (1) (H3L = N'-(2-hydroxy-3-methoxybenzylidene)-2-hydroxybenzo-hydrazide), has been prepared by using Schiff base ligand and characterized by X-ray single crystal diffraction, FT-IR, elemental analysis and TG analysis. The complex contains a pseudo-cubic Cu4O4 skeleton which is further arranged into micropores 3D supramolecular framework via multiple C-H center dot center dot center dot pi and C-H center dot center dot center dot O interactions. Fitting the temperature dependent magnetic susceptibility of 1 confirms an antiferromagnetic behavior with J = -37.46 K and J' = -2.45 K.
