This paper describes the X-ray crystal structure analysis of a cholesteryl ester solid solution, cholesteryl decanoate/cholesteryl laurate, grown from a bulk concentration with molar ratio 0.56/0.43. The unit cell is monoclinic with a = 12.969, b = 9.048, c = 31.137 A, and beta = 91.12 degrees and the space group P2(1) with Z = 4 (two molecules per asymmetric unit). The cell constants closely represent an average value of crystal parameters for the two pure components (hence, nearly…

The room-temperature crystal structure is very much like that of cholesteryl laurate monolayer I packing, in the form where the esterified fatty acid chains are fully extended, with no salient sign of conformational disorder seen in this binary solid.
The crystal structure of cholesteryl laurate at 298 K
Cholesteryl laurate, C39H6802, is monoclinic, space group P2~ with cell dimensions a = 12.989 (8), b = 9.008 (5), c = 32.020 (14) A, fl = 91.36 (5) °, and Z = 4 (two molecules in the asymmetric unit,
Conformation and packing of unsaturated chains in cholesteryl linolelaidate at 123 K.
At 123 K, crystals of cholesteryl trans-9-trans-12-octadecadienoate (cholesteryl linolelaidate, C47H76O2) are monoclinic, space group P2(1) with cell dimensions a = 13.03(3), b = 8.76(2), c =
Conformation of the oleate chains in crystals of cholesteryl oleate at 123 K.
At 123 K, crystals of cholesteryl cis-9-octadecenoate (cholesteryl oleate, C45H78O2) are monoclinic, space group P2(1) with unit cell dimensions, which are very similar to those observed in the room temperature structure.
Conformational changes of cholesteryl palmitoleate in the crystal structure at low temperature.
Measurements of the unit cell dimensions at twelve temperatures indicate that the major changes in the crystal structure of cholesteryl palmitoleate occur in a 10 K range near 173 K.

It is apparent, however, that lower atomic occupancies at the chain ends correspond to anticipated disorder at the lamellar interface and structural refinement based on this occupancy results in a good match to the observed intensity data.
