Substituted 4-alkoxy-7-Cl-quinolines exhibiting π–π stacking

Abstract

The molecules of 4-allyloxy-7-chloroquinoline, C(12)H(10)ClNO, (I), 7-chloro-4-methoxyquinoline, C(10)H(8)ClNO, (II), and 7-chloro-4-ethoxyquinoline, C(11)H(10)ClNO, (III), are all planar. In all three structures, π-π interactions between the quinoline ring systems are generated by unit-cell translations along the a axes, irrespective of space group. These structures are the first reported for 4-alkoxyquinolines.
