Effect of overall ligand charge on Scn binding. (A) Chemical structures of, left-to-right, tren(CAM)2(1,2-HOPO), tren(CAM)(1,2-HOPO)2, and tren(1,2-HOPO)3. Stereoviews of the superposition of the three (B) tren(CAM)2(1,2-HOPO)/Scn complexes, and (C) tren(CAM)(1,2-HOPO)2/Scn complexes, in the AU of their crystal structures, styled and oriented as in Fig. 3C. (D) Stereoviews of the best two ordered complexes of apo-ENT in the complex structure with Scn, styled and oriented as in Fig. 3C. ENT could not be resolved and confidently modeled in the third complex due to static disorder.
