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.
C17H15N2O⁺·I⁻，Mr = 390.22，单斜晶系，P21/c，a = 10.017(2)，b = 8.123(5)，c = 19.074(4) Å，β = 95.86(2)°，V = 1544(2) ų，Z = 4，Dχ = 1.67 g cm⁻³，μ = 2.10 cm⁻¹，λ(Mo Kα) = 0.7107 Å，F(000) = 768，在295 K下对1236个独立反射进行测量，R = 0.04。环系的尺寸与在6H-吡啶并咔唑类似物（椭圆玫瑰树碱衍生物）中发现的那些相似。碘离子和吡啶并咔唑鎓体系通过氢键相连。平面的7H-吡啶并咔唑阳离子形成大致平行于b的堆积。堆积之间的相互作用通过弱范德华力发生。
