Abstract

Cholesteryl formate$(HCOOC_{27}H_{45})$ is monoclinic, space group $P2_1$ with a=15.757(1), b=6.073(1), c=13.592(2) ${\AA},{\beta}=94.1(1)^{\circ},Z=2.$ Intensities were measured, using an automatic diffractometer with graphite-monochromated $Cu-K{\alpha}$ radiation. The structure was solved by a direct method and refined by least-squares method. The final R factor was 0.087 for 1640 observed reflections. There are no unusual bond distances and angles. The molecules are arranged in antiparallel array forming monolayers of thickness $d_{100}=15.757{\AA}.$ Adjacent cholesteryl ring groups by the translation operation along the b axis.
