Abstract
The X-ray crystal structures of two ciprofloxacin compounds, viz. [Cu(cfH)2(Cl)2] · 2MeOH · 6H2O (2) and [Cu(cfH)(phen)Cl]BF4 · 4H2O (3) are reported. Complex (2) has a distorted octahedral geometry, whereas for the nitrogen adduct (3) a distorted square–pyramidal geometry is seen. Significant enhancement in the antimycobacterial activity of the copper conjugates correlates with their copper redox couples (Cu2+ /Cu+) probably due to its relevance to intracellular accumulations and subsequent role in generating oxidative stress.
