Stereoview image of a crystal structure of 11 (yellow) bound to PAN(cyan) superposed with a previously published structure (PDB ID: 4M5U) of 5-(4-(1H-tetrazol-5-yl)phenyl)-6-(4-fluorophenyl)-3-hydroxypyridin-2(1H)-one (green). Metal-coordinating bonds are depicted as black dashed lines whereas hydrogen or electrostatic bonds are depicted in blue. Electron density calculated from an omit map is contoured at 4.0σ (blue mesh).
