Özet
The title compound, C34H58O2, consists of cholesteryl and heptanoate units, in which the six-membered rings adopt chair and twisted-boat conformations while the five-membered ring adopts an envelope conformation. In the crystal, the molecules are aligned along the a-axis direction and stacked along the b-axis direction. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H center dot center dot center dot H (92.4%) and H center dot center dot center dot O/O center dot center dot center dot H (6.1%) interactions. van der Waals interactions are the dominant interactions in the crystal packing. Density functional theory (DFT) optimized structures at the B3LYP/ 6-31 G(d) level are compared with the experimentally determined molecular structure in the solid state. The HOMO-LUMO behaviour was elucidated to determine the energy gap, and the molecular electrostatic potential (MEP) of the compound was investigated.
