Figure 2
The packing of the complexes showing the hydrogen bonding between the H4A amine hydrogen atom and the N3 (x, y + 1, z) atom on a neighboring qdt ligand as well as the sandwich orientation between adjacent qdt ligands and the distance (Å) between centroids of two qdt rings. Displacement ellipsoids are drawn at the 50% probability level; the dmso solvate is omitted for clarity. |
