## Abstract The singleβcrystal Xβray structures of speciophylline, mitraphylline, and rhynchophylline, oxindole alkaloids from the Peruvian climbing vine __Uncaria tomentosa__ (Rubiaceae), were determined. The three compounds show Nβ β β Hο£ΏN hydrogen bonding, which has not been observed in the crystal

The crystal structure of cY-panose [@a-D-glucopyranosyl-(1-+6)-O-a-Dglucopyranosyl-( l-4)-cY-D-glucose], (C,sOIhH3J, has been established by direct methods from 1491 independent reflections, and refined to a final R-value of 0.077. The crystal belongs to the monoclinic system, space group P2,, and
A series of new copolymers of tetrafluoroethylene (TFE) and hexafluoropropylene (HFP) containing up to 50 mol % of the hexafluoropropylene comonomer have been investigated with respect to chain conformation and crystal structure using wide-angle X-ray diffraction (WAXD). Increasing HFP content leads
