Non-ambient crystallography - is extreme becoming common?

Non-ambient conditions are used with increasing regularity in structural studies of crystals and functional materials - this editorial summarizes very briefly the history of environment devices and describes selected recent achievements in this field.

Isothermal and isochoric crystallization of highly hygroscopic pyridine N-oxide of aqueous solution

An oil-like aqueous solution of highly hygroscopic pyridine N-oxide (PNO) has been compressed in a diamond–anvil cell and single crystals of PNO have been grown under isothermal and isochoric conditions. The PNO anhydrate ambient-pressure structure is stabilized by CH...O contacts up to 2 GPa at least.

Structure–melting relations in isomeric dibromobenzenes

The crystal structures of three isomeric dibromobenzenes have been inspected and the relations between the short intermolecular Br...Br contacts, and characteristic bulk properties discussed. The ortho and meta isomers have been crystallized under low-temperature and high-pressure conditions.
