Figure 1
The molecular structure and the atom-labeling scheme for (1) [the atom labeling for (2) is identical, with Cs1 and Cs2 instead of Rb1 and Rb2], with displacement ellipsoids drawn at the 50% probability level and the N—H⋯N hydrogen bond shown as a dashed line. [Symmetry code: (i) x, y + 1, z.] |
