| Abstract: | A fluorophore‐labelled copper(II) complex, aquabis(dimethylformamide‐κO )(perchlorato‐κO )2‐(quinolin‐2‐yl)‐1,3‐oxazolo4,5‐f ]1,10]phenanthroline]copper(II) perchlorate monohydrate, Cu(ClO4)(C22H12N4O)(C3H7NO)2(H2O)]ClO4·H2O, has been synthesized and characterized. A cyclic hydrogen‐bonded water–perchlorate anionic cluster, i.e. (ClO4)2(H2O)2]2−, has been identified within the structure. Each cyclic anionic cluster unit is interconnected by hydrogen bonding to the cation. The cations join into an infinite hydrogen‐bonded chain running in the 010] direction. Furthermore, interaction of the complex with calf‐thymus DNA (CT‐DNA) and cellular localization within the cells was explored. Spectroscopic studies indicate that the compound has a good affinity for DNA and stains the nucleus of the cells. |
