Abstract

The structures of 3-(3-bromopropyl)-5-nitro-1 H -indole, C 11 H 11 N 2 O 2 Br, and 3-(3-hydroxypropyl)-5-nitro-1 H -indole, C 11 H 12 N 2 O 3 , have the nitro groups rotated out of the plane of the indole backbone by 6.6 (3)° for the bromo compound and 5.4 (2)° for the OH compound. The propyl subunits adopt the synclinal–synclinal conformation along the internal C sp 3 carbons consistently in both structures. Bond distances to the terminal substituent on the propyl group are: Br—C 1.955 (2) and O—C 1.428 (2) Å.

Study Snapshot
