μ-1,3-Acetamide or acetate bridged, symmetric and asymmetric dicopper(II) complexes viz [Cu2(P1-O−)(NHAc−)](ClO4)2 (1), [Cu2(P2-O−)(OAc−)](ClO4)2 (2) and [Cu2(P2′-O−)(OAc−)(H2O)](ClO4)2 (3) were synthesized by employing classic dinucleating ligands; P1-OH, P2-OH (symmetric), and P2′-OH (asymmetric) having trivial differences in their ligand frame work. Solid state structures of these complexes were determined by X-ray crystallography. In solution, they were also characterized by various spectroscopic techniques, which includes ESI-MS, FT-IR, optical, solution magnetic moment, paramagnetic 1H NMR and EPR. The solution magnetic moment of these complexes at room temperature suggests a weak magnetic interaction between the two Cu(II) centers.
