Abstract

The fully ordered high-pressure crystal structure of cyclopentanol (C 5H10O) has been solved using single-crystal X-ray diffraction techniques on station 9.8 at the SRS Daresbury Laboratory. At pressures above 1.5 GPa, cyclopentanol crystallizes in the monoclinic P2 1/c space group with a = 17.882 (3), b = 5.4573 (3), c = 9.6817 (14) Å, β= 104.699 (8)° and Z′ = 2. The crystal structure is characterized by the formation of hydrogen-bonded molecular chains, denoted C22(4) in graph set notation, which lie parallel to the crystallographic c-axis, with the molecules adopting a pseudo fourfold arrangement around the central core of hydrogen bonds.
