Crystallographic analysis and structural conformational study of conessine: A steroidal alkaloid

摘要

The compound crystallizes in the orthorhombic crystal system with space group P2_12_12_1 having unit cell parameters: a=10.840(13), b=10.896(6), c=18.903(6) A and Z=4. The crystal structure was solved by direct method using single crystal X-ray diffraction data collected at room temperature and refined by full-matrix least-squares procedures to a final R-value of 0.062 for 1044 observed reflections.
