摘要: Different physicochemical studies were undertaken with polycrystalline samples of the complex [Cu2(carnosine)2(H2O)2].2H2O. The infrared spectrum was discussed in comparison that free carnosine and on basis known structural data. Magnetic susceptibility measurements performed between 4.2 300 K, showing an effective magnetic moment 1.79 BM. Both electronic (reflectance) ESR spectra compatible existence a dx2-y2 ground state. axial reversed could be explained very weak interdimeric coupling mechanism. electrochemical behavior, investigated by cyclic voltammetry, shows possesses high redox stability. possible SOD-like activity tested using NBT/superoxide reduction assay. results show negligible SOD activity.
