Crystals of the ternary alpha-cyclodextrin-acetonitrile hexahydrate inclusion complex belong to the orthorhombic space group P212121 with unit cell dimensions a = 9.479(2), b = 14.323(4), c = 37.397(9) A. Refinement against 4202 X-ray diffraction data converged at R=0.059. The alpha-cyclodextrin macrocycle forms a regular torus which is stabilized by(More)
A single-crystal neutron diffraction study of cyclodecaamylose (CA10) was carried out at 20 K. CA10 crystallizes with 27.18 water molecules [(C(6)H(10)O(5))(10).27.18H(2)O] in space group C2 with unit-cell constants a = 29.31 (5), b = 9.976 (10), c = 19.34 (2) A, beta = 121.07 (2) degrees. The asymmetric unit contains a half molecule of CA10 and 13.59 water(More)
Octakis(2,3,6-tri-O-methyl)-gamma-CD (TRIMEG) cocrystallized at 18 degrees C with 4.5 water molecules in the orthorhombic space group P2(1)2(1)2(1), unit cell dimensions a = 10.7879(3), b = 29.0580(9), c = 32.2909(11) A. The TRIMEG macrocycle is in a 'round' form with all glucose units oriented syn, and one O-6-CH3 methoxy group points 'toward' the(More)
Hexakis(2,6-di-O-methyl)-alpha-cyclodextrin (DIMEA) crystallizes from 1:1 water-acetonitrile as DIMEA-acetonetril-dihydrate in the orthorhombic space group P2(1)2(1)2(1), unit cell dimensions a = 14.2775(5), b = 15.7312(5), c = 31.1494(11) A. Refinement of the structure against 5540 X-ray diffraction data converged at an R factor of 0.083. The macrocycle(More)
