Why?

This is my favorite crystal structure because the material family had been studied for almost a century, however the structure (cubic perovskite) was not consistent with the properties (ferroelectric response) and I had the opportunity to solve the structure for my PhD. We found that it had a massive unit cell and it added to a growing number of non-cooperative octahedral tilted perovskites. In a nut shell it is my favorite because I feel like I got to see a glimpse into K3MoO3F3 before anyone else.—Allyson Fry
