Figure 1
The molecular configuration and atom-numbering scheme for the 4-(phenyldiazenyl)anilinium cation and 2-carboxy-6-nitrobenzoate anion in (I). Displacement ellipsoids of the major-occupancy atoms are drawn at the 40% probability level and H atoms are shown as small spheres of arbitrary radii. The inter-ion hydrogen bond is shown as a dashed line. The longitudinal rotationally disordered isotropic atoms of the cation [N1′, N11′, C1′–C6′, C11′–C61′ and their attached H atoms; site-occupancy factor = 0.225 (8)] are also joined by dashed lines. |
