【摘要】 α-氯代桂皮酰另丁胺（反式异构体）的分子式为C₁₃H₁₅ONCl,属正交晶系,空间群为P_bca,a=18.842（0.006）,b=14.076（0.006）,c=10.077（0.003）,晶胞内分子数z=8。用RASA-IIS四圆衍射仪收集衍射强度数据,独立的可观察衍射点929个。用直接法（MULTAN-80）测定其结构。以全部可观察点强度数据用准对角矩阵最小二乘法修正结构参数,R=0.088更多还原

【Abstract】 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)A, b=14.076 (0.006)A, c=10.077 (0.003)A. 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.更多还原
