摘要

The molecular and crystal structures of the 4-hydroxy derivative of (3R,6R)-3-methyl-6-isopropyl-2-(4-phenylbenzylidene)cyclohexanone are determined by X-ray diffraction analysis. Single crystals are orthorhombic, a = 9.147(2) angstrom, b = 12.959(2) angstrom, c = 15.695(5) angstrom, V = 1860.4(7) angstrom(3), Z = 4, and space group P2(1)2(1)2(1). The cyclohexanone ring in the crystal structure has an asymmetric chair conformation. The puckering parameters are as follows: the puckering amplitude S is 0.91, and the puckering angles theta and Psi are equal to 20.2 degrees and 10.4 degrees, respectively. It is established that the enone fragment and the cyclohexanone ring in molecules are flattened considerably. In the crystal structure, the molecules are linked by the OH center dot center dot center dot O=C< hydrogen bonds (bond length, 1.85 angstrom). The structural features and the strength of the hydrogen bonds for the compound under investigation and its analogue with one benzene ring are compared using the X-ray diffraction and IR spectroscopic data.
