Abstract
In the crystal structure of ethyl (Z)-3-{[3-(3,5-dichloro-2,4,6-trimethylph enyl)isoxazol-4-yl]-2-butenylidene}carbazate-ethyl acetate solvate, C19H21C l2N3O3.0.34- C4H8O2 (R-1 = 0.072, wR(2) = 0.228), the host molecules are li nked by intermolecular N-H ... N hydrogen bonds, giving rise to infinite ch annels which contain molecules of ethyl acetate. Packing potential energy c alculations carried out for host-guest model crystals account for the disor der of the solvent molecules in the crystal state.
