SXD at Mbar pressures
The fully ordered high-pressure crystal structure of cyclopentanol (C5H10O) has been solved using single-crystal X-ray diffraction techniques on station 9.8 at the SRS Daresbury Laboratory. The crystal structure is characterized by the formation of molecular chains, denoted C(4) in graph set notation, with the molecules adopting a pseudo fourfold arrangement around the central core of hydrogen bonds.
SXD at Mbar pressures
The structure of hexagonal L-cystine consists of pairs of hydrogen-bonded layers connected by disulfide bridges. The conformation about the bridges changes on compression to 3.7 GPa as the C—S—S—C units act like springs; other changes can be understood by examination of the distribution of voids in the ambient pressure structure.
