(E)-N′-(5-Chloro-2-hydroxybenzylidene)-4-(8-quinolyloxy)butanohydrazide monohydrate

The crystal of the title Schiff base compound, C20H18ClN3O3·H2O, was twinned by a twofold rotation about (100). The asymmetric unit contains two crystallographically independent molecules with similar conformations, and two water molecules. The C=N—N angles of 115.7&am...
