Crystal structure of ferroelectric glycine silver nitrate

Abstract

An x-ray structural anal. indicates that glycine Ag nitrate crystallizes in the monoclinic space group P21/a: a 5.451, b 19.493, c 5.541 .ANG., and b 100 Deg 12'; Z = 4. Below the Curie point, the a-glide vanishes and the space group is P21. The cell dimensions at -140 Deg are a 5.362, b 19.391, c 5.536 .ANG., and b 100 Deg 12'
