Bidentate interaction of fluoroquinolone with Tc. Structures of 99mTc-ciprofloxacin are shown using TcO+3 (4) and TcN+2 (16) cores that complex with ciprofloxacin through a two-bidentate coordination. Both structures have a square planar pyramid geometry, with the C4-oxygen of ciprofloxacin at the geometrical apex and an oxygen or nitrogen at the pyramid base of the Tc core.
