Crystal structure of tert-butyl 3,6-diiodocarbazole-9-carboxylate

Abstract

The molecular structure of tert-butyl 3,6-diiodocarbazole-9-carboxylate, C17H15I2NO2, 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 intermolecular π–π interactions, as well as both type I and type II intermolecular I...I interactions.
