Visualizing and teaching crystallographic symm­etry using Jmol

The Jmol Space Group Symmetry Visualizer (https://spacegroups.symotter.org) is an online resource for the visualization of crystallographic symm­etry built around the versatile Jmol application and represents a unique resource for students and educators in crystallography and researchers using crystallographic methods.

Structure and intermolecular interactions of the rare amide–pyridine synthon: a cocrystal of nicotinamide and 2-chloro-3-hydroxypyridine

Considering its low occurrence in the Cambridge Structural Database, is the amide–pyridyl synthon easy to form, and what structural factors affects its inter­action energy and its subsequent formation?

Diffuse scattering in silver hypo­diphos­phate, Ag₄(P₂O₆), probed by 3D ED

A 3D ED study of silver hypo­di­phos­phate, Ag₄(P₂O₆), has revealed diffuse scattering and was used to model real structure.

Study of a new fluorinated com­pound: variable-tem­per­ature crystallography, thermal expansion, theoretical calculations and biological assays

A new crystal structure of butane-1,4-diyl bis­(tri­fluoro­methane-1-sulfonate) [Bu(OTf)₂] has been determined. The mol­ecular and crystal structure were characterized by single-crystal X-ray diffraction supported by com­putational studies. In the solid state, the structure is primarily stabilized by fluorine–fluorine and chalcogen inter­actions.

An Mn²⁺-based organic–inorganic hybrid with spatially separated charge transfer for efficient green phospho­rescence

A novel Mn^II-based hybrid material exhibits efficient green phospho­rescence with a millisecond-scale lifetime via a spatially separated charge-transfer state. This work demonstrates a general design strategy for achieving long-lived luminescence from earth-abundant metals.
