The p-chloro benzoyl piperidine. C12H14 ONCL crystal belongs to the orthorhombic system. The space group is P21 21 21 with α=11.490(6)?, b = 10.462(5)?, c=9.928(5)?, z = 4 and calculated density Dc= 1.2410 gcm-3. The intensity data were collected on a Philips PW-1100 diffractometer. With the chlorineatom position found from Patterson method, the structure was determined by Fourier synthesis and refined by full-matrix least square method to a final R value of 0.093 for 697 reflexions. The hydrogen atom coordinate parameters were obtained from difference Fourier synthesis. The absolute configuration of molecule was determined by anomalous scattering method.
