Laplacian of the electron density in the N5—C4—N3—N4 plane. (a) Experimental and (b) theoretical map; (c) lone pairs of the Cl− anion and (d) lone pair of the N3 atom in the C3—N3—C4 plane. (c) and (d) are experimental. Solid blue and red lines represent the positive and negative contour lines, respectively. Contour levels 2, 4, 8, 10n, n = −1, 0, 1. |
