A review. Diffraction methods are a powerful tool to investigate the crystal structure of
organic compounds in general and their hydrates in particular. The laboratory standard …

A series of protonated bipyridinium compounds has been synthesized and their crystal
packing is discussed in terms of N–H… X contacts (X 5 O, Cl) together with p–p and Cl2… p …

A series of cocrystals and salts of succinic and fumaric acids and the isomers of lutidine
have been prepared. The crystal structures of six lutidine–succinic acid cocrystals, four …

The anion coordination chemistry of two protonated urea-based ligands, N-(2, 4-
dimethylphenyl)-N′-(3-pyridy1) urea (1) and N-(2, 6-dimethylphenyl)-N′-(3-pyridy1) urea …

A series of 1, 1′-binaphthalene-2, 2′-diyl phosphate (BNPPA−) salts have been
synthesized. Their crystal packings show a separation of the hydrophobic naphthyl and …

Drug formulations of anhydrous solid forms are generally preferred over hydrated forms.
This is due to the risks of low exposure and unacceptable physical and chemical stability in …

Three novel carboxylate salts, phenylethylammonium fumarate-fumaric acid,
phenylethylammonium succinate-succinic acid and anilinium fumarate-fumaric acid, have …

High-pressure crystallisation of an aqueous solution of the GABA analogue gabapentin at
0.8 GPa resulted in the formation of a previously unknown heptahydrate form, whose …

The crystal energy landscapes of the salts of two rigid pharmaceutically active molecules
reveal that the experimental structure of amantadine hydrochloride is the most stable …

A number of porous salts based on the pamoate anion in combination with lutidinium or
picolinium cations have been characterised. One salt undergoes single-crystal to single …
