Solid solutions based on BaZn2Si2O7 with thermal expansions from negative to highly positive – a review
Replacing Ba2+ by Sr2+ stabilizes the high temperature phase and leads to zero or negative thermal expansion. Replacing Zn2+ by Mg2+ or Co2+, Ni2+, Mn2+, Cu2+ shifts the phase transition to higher temperatures and leads to high thermal expansion.

Co-crystal synthesis of 2- and 4-mercaptopyridines with thiourea and its analogue, trithiocyanuric acid
For the first time mercaptopyridine co-crystals are reported as a result of the cross-crystallization of two mercaptopyridines with thiourea and trithiocyanuric acid. In one case, the co-crystal was needed to be obtained under dark room conditions.

Engineering of a kinetically driven phase of phenoxazine by surface crystallisation
Surface crystallisation yields an unknown polymorph of the phenoxazine molecule. Tuning the crystallisation conditions causes a defined crystal growth of either the thermodynamically stable phase or the kinetic phase observed exclusively within thin films.

Intermolecular interactions in the solid-state structures of isoflavones: the relationship between supramolecular structure, torsion angle, and macroscopic properties
The different macroscopic properties of closely related isoflavones were associated with the occurrence of intermolecular interactions and different torsion angles in the solid-state.

Metal ions impact on the isostructurality and properties of 2D coordination polymers
The degree of isostructurality of seven coordination polymers and the effect of metal ions on their properties were studied. Crystallographic, photoluminescence, NLO and thermoelectric analyses of the entire series were carried out.

p-Sulfonatocalix[4]arene dimers encapsulate mono- and multicharged imidazolium guests within antiparallel bilayer arrays, in one case forming unusual hydrated nanoscale channels that span this common arrangement.

Hydrothermal formation of bismuth-titanate nanoplatelets and nanowires: the role of metastable polymorphs
Nanowires and perovskite crystallites form in the initial stages of hydrothermal synthesis. In continuation, the perovskite dissolves at lower NaOH concentrations, whereas at the higher concentrations the perovskite transforms to the nanoplatelets.

Exploring the influence of polymorphism and chromophore co-ligands on linkage isomer photoswitching in [Pd(bpy4dca)(NO2)2]
The presence of non-innocent chromophore ligands in photoswitches can limit functionality. This photocrystallographic study shows how the negative impact of such ligands can be mitigated by control of excitation conditions, maximising photoswitching.
