Figure 1
Overall structure of L-d(CGCGCG)2/Cad2+/K+ highlighting the interactions between the cations and the DNA molecules within the asymmetric unit (orange) and two other symmetry-related DNA molecules (light orange): i (−x, y + 1/2, −z + 1/2) and ii (x + 1/2, −y + 1/2, −z). Potential polar interactions with the Cad2+ cation (stick model) are marked as red dashed lines and K+ is shown as a purple sphere with the coordination bonds marked as black dashed lines. |
