Two new mono- and one binuclear μ-nitrato bridged Cu(II) complexes [Cu(L)(HL)]ClO4 (1), [Cu(HL)(NO3)(H2O)]2NO3•H2O (2) and [Cu2(L2)(μ-NO3)2] (3), with an unsym. NNO donor Schiff base (HL) were synthesized and characterized by elemental anal., FTIR, CV, UV-visible and EPR spectroscopy. Their mol. structures were also determined by single crystal x-ray crystallog. In the binuclear complex 3, the Cu··· Cu distance is 3.494 Å. In 1, 2 and 3, the Cu(II) centers have distorted square pyramidal geometry (τ5 = 0.05-0.17). Evidence of weak π···π stacking intermol. interactions along with other noncovalent interactions (H bonding) was observed by analyzing the resp. crystal structures of the complexes. Thus, these H bonds, π···π stacking interactions and other weak intermol. interactions establish as supramol. architectures a crystalline network environment. The noncovalent interactions were also studied by employing Hirshfeld Anal. The room temperature magnetic moments of the mononuclear complexes are less than the spin only values which are indicative of small interactions. Also, significant magnetic interactions were not exhibited by binuclear Cu(II) complex 3 in the variable temperature magnetic measurements. The X-band EPR spectra of all three complexes exhibit Cu(II) hyperfine structures as well as zero-field splitting which are appropriate for the triplet states of dimers. In 1 and 2, the presence of pseudo dipolar interactions is proposed. Quantum chem. calculations (DFT) were carried out on complexes 1–3 to explore the electronic and spectral properties of these newly synthesized complexes. These complexes show significant antiproliferative and SOD activity. The SOD activity measured in terms of kMcCF is in the range 4.94-12.31 (mol L)-1s-1 x 104.
