High-pressure polymorphism of cyclopentanol (C₅H₁₀O): the structure of cyclopentanol phase-V at 1.5 GPa

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.
