See what you will probably never see in reality, thanks to the PCOD
Three-dimensional borosilicate models (not DFT-optimized) as predicted
Models selected among 3603 CIFs including 3D,
2D and 1D
borosilicates - BO3 triangles connected to SiO4
tetrahedra exclusively by corner-sharing - listed according to increasing
framework density (FD)
Not exhaustive list (more will be added during the next weeks, maybe)...
