The Crystallography Open Database (COD) is an ongoing initiative by crystallographers to gather all published inorganic, metal–organic and small organic molecule structures in one database, providing a straightforward search and retrieval interface. The COD adopts an open-access model for its >80 000 structure files.

The crystal structure of vulgarone B (2,6,6,11-tetramethyltricyclo[5.4.0.02,8]undec-10-en-9-one), a carbocyclic sesquiterpene with the formula C15H22O, is reported. All intramolecular geometric parameters are as expected. The molecule contains a four-membered ring, in which all atoms are stereogenic. The 1,3 and 2,4 atoms of this cyclobutane are bridgehead C atoms which form part of six-membered and seven-membered rings.

The crystal structure of 3-pentafluorothiopropionic acid, C3H5F5O2S, is reported. In the solid, the acid forms a dimeric unit, in which two molecules are held together by strong hydrogen bonds. The two molecules are arranged across an inversion center. The average literature structural parameters for the organic/organometallic pentafluorothio group are reported, and a short discussion of the geometry of this molecule in this context is given.
