Structure and pseudosymmetry of cholesterol at 310 K

Structure and pseudosymmetry of cholesterol at 310 K The structure of cholesterol above the (304.8 K) phase transition, previously published in preliminary form [Hsu & Nordman (1983). Science, 220, 604–606], has been fully refined using augmented X‐ray data. The crystals are triclinic, space group P1, with (reassigned) cell parameters a = 27.565 (10), b = 38.624 (16), c = 10.748 (4) Å, α = 93.49 (3), β = 90.90 (3), γ = 117.15 (3)°, and V = 10151 (7) Å3. The unit cell contains Z = 16 molecules, of which eight are related to the other eight by unusual twofold rotational pseudosymmetry. The structure is related to the room‐temperature phase, with Z = 8, by a rearrangement of some of the molecules, and by a doubling of the a axis. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acta Crystallographica Section B: Structural Science, Crystal Engineering and Materials Wiley

Abstract

The structure of cholesterol above the (304.8 K) phase transition, previously published in preliminary form [Hsu & Nordman (1983). Science, 220, 604–606], has been fully refined using augmented X‐ray data. The crystals are triclinic, space group P1, with (reassigned) cell parameters a = 27.565 (10), b = 38.624 (16), c = 10.748 (4) Å, α = 93.49 (3), β = 90.90 (3), γ = 117.15 (3)°, and V = 10151 (7) Å3. The unit cell contains Z = 16 molecules, of which eight are related to the other eight by unusual twofold rotational pseudosymmetry. The structure is related to the room‐temperature phase, with Z = 8, by a rearrangement of some of the molecules, and by a doubling of the a axis.
