Abstract
The structure of the title compound 6,14,22-tribromo-19-ethoxy-2,10,18-triazahexacyclo[18.4.0.0 2,11 .0 3,18 .0 4,9 .0 12,17 ]tetracosa-1(24),4(9),5,7,12(17),13,15,20,22-nonaene monohydrate, C 23 H 18 Br 3 N 3 O.H 2 O, a bisanhydro trimer hydrate formed from the acid-catalyzed self-condensation of 2-amino-5-bromobenzaldehyde, substantiates the geometry proposed for the similar trimer of o-aminobenzaldehyde (OAB). The tricyclic molecule is an ethoxy derivative rather than a hydroxy derivative as previously observed with OAB. Formation of the ethoxy derivative is a direct result of the condensation reaction having been carried out in ethanol
