STUDIES ON THE CRYSTAL STRUCTURE OF BAIMUXIANGIC ACID

The Baimuxiangic acid C₁₅H₂₄O₃ crystal belongs to the monoclimic system, space group is C2, with a=12.150 (3), b=10.827 (4), c=11.344 (4), β=111.78(2)°,Z=4, calculated density Dc=1.208 gcm^-3 The intensity data were collected on the RIGAKU diffractometer. The structure was determined by direct method (MULTAN 80), and has been refined by full-matrix least-squares method to a final R value of 0.060 for 2052 reflexions. The H-atom coordinate parameters were found from difference Fourier synthesis.
