Three 9-[(E)-2-(4-halogenophen­yl)vin­yl]-9H-carbazoles

M. Kubicki, W. Prukala and B. Marciniec

Abstract: The crystal structures of 9-[(E)-2-(4-fluoro­phen­yl)vin­yl]-9H-carbazole, C20H14FN, (I), 9-[(E)-2-(4-chloro­phen­yl)vin­yl]-9H-carbazole, C20H14ClN, (II), and 9-[(E)-2-(4-bromo­phen­yl)vin­yl]-9H-carbazole, C20H14BrN, (III), are determined mainly by van der Waals forces. The chloro and bromo derivatives are highly isomorphous, while the fluoro derivative has a different packing mode. Weak C-H...X inter­actions are also involved in the crystal packing. The mol­ecular structures of the three compounds are similar, with relatively large twist angles of ca 55° between the carbazole and benzene planes.

Formula: C20H14FN, C20H14ClN and C20H14BrN
