“…The presence of the lone electron pair makes the structure highly compressible. This phenomenon has also been documented for other compounds with a lone electron pair cation, such as iodates, which have similar bulk moduli to the polymorph of Pb 2 SnO 4 described by space group Pbam . The relationship we found can be used to estimate the bulk moduli of other M 2 SnO 4 stannates.…”

The pressure-induced structural evolution of Ca 2 SnO 4 , Sr 2 SnO 4 , and Zn 2 SnO 4 has been characterized by powder X-ray diffraction up to 20 GPa using the ALBA synchrotron radiation source and density functional theory calculations. No phase transition was observed in Ca 2 SnO 4 and Zn 2 SnO 4 in the investigated pressure range. The observation in Zn 2 SnO 4 solves contradictions existing in the literature. In contrast, a phase transition was observed in Sr 2 SnO 4 at a pressure of 9.09 GPa. The transition was characterized as from the ambientcondition tetragonal polymorph (space group I4/mmm) to the low-temperature tetragonal polymorph (space group P4 2 /ncm). The linear compressibility of crystallographic axes and room-temperature pressure−volume equation of state are reported for the three compounds studied. Calculated elastic constants and moduli are also reported as well as a systematic discussion of the high-pressure behavior and bulk modulus of M 2 SnO 4 stannates.

“…It is isomorphic to the mineral wolframite - (Fe,Mn)WO 4 – sharing the structure with several tungstates, including CoWO 4 , CdWO 4 , MgWO 4 , MnWO 4 , and ZnWO 4 . High-pressure studies have contributed to the understanding of the structural and electronic properties of wolframites. − High pressure (HP) can substantially modify the structural and electronic properties of materials favoring a deep understanding of them . NiWO 4 is one of the wolframites that has been less studied under compression, there being only one article recently published .…”

We report an extensive study of the optical and structural properties of NiWO4 combining experiments and density functional theory calculations. We have obtained accurate information on the pressure effect on the crystal structure determining the equation of state and compressibility tensor. We have also determined the pressure dependence of the band gap finding that it decreases under compression because of the contribution of Ni 3d states to the top of the valence band. We report on the sub-band-gap optical spectrum of NiWO4 showing that the five bands observed at 0.95, 1.48, 1.70, 2.40, and 2.70 eV correspond to crystal-field transitions within the 3d 8 (t 2g 6 e g 2) configuration of Ni2+. Their assignment, which remained controversial until now, has been resolved mainly by their pressure shifts. In addition to the transition energies, their pressure derivatives are different in each band, allowing a clear band assignment. To conclude, we report resistivity and Hall-effect measurements showing that NiWO4 is a p-type semiconductor with a resistivity that decreases as pressure increases.

“…It is a very wellknown fact that HP modifies interatomic bonds, triggering changes in the structural, physical, and chemical properties of materials. 19 Consequently, HP research has made relevant contributions to the understanding of the properties of materials, and consequently to the progress of materials science. 20 In order to deepen the knowledge of the properties and HP behaviour of lanthanide antimonates, we have performed a study on ytterbium orthoantimonate (YbSbO 4 ).…”
