“…In the high temperature region, the χ M T value of 300 K is 2.69 cm 3 K mol − 1 , well in agreement with the theoretical value of 2.25 cm 3 K mol − 1 for six non-interacting Cu(II) ions with S = 1/2 and g = 2.0 [45]. When the temperature decreases, the χ M T value decreases gradually to 0.531 cm 3 K mol − 1 at 2 K. The χ M T versus T curve accords with an antiferromagnetic behavior of hexanuclear copper(II) complexes [41,46,47]. The best linear fit according to the Curie-Weiss law in the temperature range of 50-300 K yields C = 2.90 cm 3 K mol − 1 and a Weiss constant θ = −26.62 K (see the inset of Fig.…”

Two new copper(II) carboxylate complexes with 2,2′‐bipyridine and para‐nitrophenyl acetate (complex 1) and phenyl acetate (complex 2) have been synthesized; isolated in quantitative yield; and characterized using fourier‐transform infrared spectroscopy (FT‐IR), electron paramagnetic resonance, absorption spectroscopy, electrochemistry, and powder and single crystal X‐ray diffraction (XRD) techniques. Being mononuclear, the geometry around copper in complex 1 is a Jahn–Teller distorted octahedral, while complex 2 is binuclear with slightly distorted square pyramidal geometry around both copper ions. Powder XRD indicated several peaks in spectra of both complexes, which coincided with their theoretical spectra. FT‐IR results of the carboxylate stretching frequency were in accordance with the single crystal structure data. Electron paramagnetic resonance spectra of complexes 1 and 2 yielded g┴ values of 2.06161 and 2.24623 and 1.94959, respectively, indicating a localized electron in b1 (d x2–y2‐orbital). Ultra‐violet (UV)–visible spectroscopy and electrochemistry helped in characterization, as well as in deoxyribonucleic acid (DNA)‐binding ability of the complexes, yielding DNA‐binding constant values = 1.351 × 104 and 1.361 × 104 and 1.820 × 104 and 2.426 × 104 M−1, respectively, for complexes 1 and 2. The complexes demonstrate good biological potential.
