Solid state structures hydrogen bonding

The crystal and molecular structure of l,3-dimethyl-8-azaxanthine monohydrate has been determined by X-ray diffraction. The compound exists as the N-8-H tautomer in the solid state, and hydrogen-bonded dimers are formed. Molecular orbital computations have been performed for this... [Pg.104]

Bulk drug 13C, 31P, 1SN, 25Mg, 23Na Solid state structure elucidation, drug-excipient interaction studies (variable temperature), (pseudo)polymorphic characterization at the qualitative and quantitative level, investigation of hydrogen bonding with salt compounds... [Pg.111]

The solid-state structure of ort o-carborane was determined for the first time in 1996 featuring HMPA as a weak hydrogen bond adduct in the solid state.569 The geometry of ort o-carborane, I T BjoH, is a distorted icosahedron with a bond of 1.62 A between the cage carbons (C1-C2). This bond is remarkably elastic being elongated up to 1.85 A... [Pg.91]

The two-point interaction between POin cavitands and alcohol guest was exemplified by the solid state structure of the 16(f) C2H50H complex showing hydrogen bond to the P=0 group and CH interactions between the... [Pg.73]
