Cholesteryl isobutylcarbonate

Y. J. Park, J. Bae and M. S. Lah

Abstract: Cholesteryl isobutylcarbonate, C₃₂H₅₄O₃, contains two molecules (A and B) in the asymmetric unit. The isobutylcarbonate chain of molecule A and the isoprenoid tail of molecule B are each conformationally disordered over two positions. The two distinct molecules form separate stacks along the screw axes so that they are arranged in an antiparallel array, forming monolayers with a thickness of d₀₀₁ = 19.412  Å. The central regions of the monolayers are characterized by efficient molecular packing and are separated by interface regions, which are more loosely packed.
