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