Cholesteryl decanoate (C37H64O2) is monoclinic, space group P2I, with cell dimensions a = 12.931 (6), b = 9.066 (2), c = 30.22 (1) A, beta = 91.14 (4) degrees, and Z = 4. The atomic coordinates from cholesteryl laurate were used in an initial trial structure which was refined by block diagonal least-squares methods with 1846 observed X-ray reflections (R = 0.129). Molecules A and B have almost fully extended conformations, except at the ester bonds and towards the end of the decanoate B chain. The molecules are arranged in antiparallel array forming monolayers of thickness d001 = 30.22 A, with the molecular long axis making an angle of about 67 degrees with the layer interface. The crystal structure is very similar to that of cholesteryl nonanoate and cholesteryl laurate.
