Both 1 and 2 are tetranuclear Cu4O4 species with closed cubane core and double-open cubane like core structure, respectively. On the other hand complex 3 is a 1D polymeric chain, where Schiff base chelated dinuclear copper units are linked through terephthalate ions. C-H π interactions among the 1D polymeric chains form a 2D supramolecular architecture.
