| Abstract: | A fluorophore‐labelled copper(II) complex, aquabis(dimethylformamide‐κO )(perchlorato‐κO )[2‐(quinolin‐2‐yl)‐1,3‐oxazolo[4,5‐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. |
