α-CHLORO-N-SEC-BUTYI-CINNAMIDE crystal (trans) belongs to orthorhombic system. The space group is D2h15-Pbca with eight molecules in a cell of dimension α= 18.842 (0.006)?, b=14.076 (0.006)?, c=10.077 (0.003)?. The intensity data were collected on RASA-IIS four-circle diffractometer. The number of independent reflexions is 929. The structure was solved by direct method (MULTAN-80). Refinement of structure parameters was achieved by block- matrix least-squares method, R =0.088.
