Zusammenfassung:	C17H15N2O+.I-, Mr = 390.22, monoclinic, P21/c, a = 10.017 (2), b = 8.123 (5), c = 19.074 (4) A, beta = 95.86 (2) degrees, V = 1544 (2) A3, Z = 4, D chi = 1.67 g cm-3, mu = 2.10 cm-1, lambda (Mo K alpha) = 0.7107 A, F(000) = 768, R = 0.04 for 1236 unique reflections measured at 295 K. Dimensions of the ring system are similar to those found in 6H-pyridocarbazole analogues (ellipticine derivatives). The iodine ion and pyridocarbazolium system are linked by a hydrogen bond. The planar 7H-pyridocarbazole cations form stacks approximately parallel to b. Interactions between stacks occur by weak van der Waals forces.
