A mononuclear complex of norfloxacin with silver(I) and its properties

Reaction of norfloxacin (H-Norf) with AgNO3 yields an unusual mononuclear complex [Ag(H-Norf)2]NO3 (1) in which the local coordination environment around Ag+ ion is approximately linear with a N–Ag–N angle of 162.1(2)°. Larger concentration of Ag+ ions was found in water solution of 1. The unique bonding in 1 may lead to the readily release of Ag+ ion from 1, and leads to better antibacterial action in topical burn treatments. Strong blue fluorescent emission of 1 was also observed.
