Some experimental observations on H--O hydrogen-bond lengths in carbohydrate crystal structures. [Methyl pyranosides]
Neutron diffraction studies of the crystal structure of the monosaccharides methyl ..cap alpha..-D-mannopyranoside, methyl ..cap alpha..-D glucopyranoside, and methyl ..cap alpha..-D-altropyranoside has revealed an unusually systematic relationship between the hydrogen-bond lengths and the type of O--H...O interaction. Five different modes of interaction between donor hydroxyl groups and acceptor oxygen atoms were represented in the study, and the hydrogen bond distances for the methyl pyranosides fell into five distinct groups separated by about 0.1 A. The H...O distances for each type of interaction were tabulated for the methyl pyranosides, ..cap alpha..-D glucose, sucrose, and ..beta.. maltose monohydrate. (DDA)
