At room temperature, monoclinic BiPb2VO6 is a polar, noncentrosymmetric, second harmonic generation active material and its crystal structure is among the more complex to be solved ab initio from powder diffraction data. In its stability range, BiPb2... Read More about Variable temperature structural study of bismuth lead vanadate, BiPb₂VO₆.

Structure and phase transitions of SnP2O7 (2002)
Journal Article
Gover, R., Withers, N., Allen, S., Withers, R., & Evans, J. (2002). Structure and phase transitions of SnP2O7. Journal of Solid State Chemistry, 166(1), 42-48

SnP2O7 is a member of the ZrP2O7 family of materials, several of which show unusual thermal expansion behavior over certain temperature ranges and which show a number of displacive phase transitions on cooling from high temperature. Here we describe... Read More about Structure and phase transitions of SnP2O7.
