The mol-ecular structure of -butyl 3,6-di-iodo-carbazole-9-carboxyl-ate, CHINO, features a nearly planar 13-membered carbazole ring with C-I bond lengths of 2.092 (4) and 2.104 (4) Å. The carbamate group has key bond lengths of 1.404 (6) Å (N-C), 1.330 (5) Å (O-C), and 1.201 (6) Å (C=O). The crystal contains inter-molecular π-π inter-actions, as well as both type I and type II inter-molecular I⋯I inter-actions.
