See what you will probably never see in reality, thanks to the PCOD
One-dimensional V2O5 models (not DFT-optimized) as
predicted by GRINSP
Construction of these V2O5 models (3D,
2D, and 1D) described in 2005 and 2010 in
refs. [1 and 8] - VO5 square pyramids or/and trigonal
bipyramids interconnected exclusively by corner-sharing. Data from the
2009 (1319 models) PCOD updates. Ordered by
increasing FD (Framework Density) : largest tunnels and biggest cavities.
Not exhaustive list (more will be added during the next weeks, maybe,
and also, much more can be obtained by running again GRINSP)...
