| Abstract: | A pentaammineazidocobalt(III) complex, Co(NH3)5N3](MnO4)2XH2O has been synthesized by an one-pot synthesis method. It was characterized by studies such as infrared (IR) and UV-visible spectroscopy. The single crystal X-ray structure analysis revealed that the title complex crystallizes in space group Cc. The cobalt center is six coordinated with slightly octahedral geometry. The supramolecular architecture is also formed by intermolecular N-H…O (anion and H2O) and Mn-O…O-H hydrogen bonds. The binding property of the cation, Co(NH3)5N3]2+ with the anion, MnO4– has also been determined (in solution phase) with the help of UV-visible spectroscopic titrations. Further, the genotoxic effects of KMnO4, Co(NH3)5N3]Cl2 and Co(NH3)5N3](MnO4)2XH2O were studied using Allium cepa root chromosomal aberration assay and it revealed that the genotoxicity of the newly synthesized complex is 1.97–1.76 fold, which is less compared to KMnO4. The order of genotoxic potential has been observed to be KMnO4 > Co(NH3)5N3](MnO4)2XH2O > Co(NH3)5N3]Cl2. |
