One-dimensional B2O3 models (not DFT-optimized) as predicted by GRINSP

Construction of these B2O3 models (3D, 2D, 1D and 0D) described in 2005 and 2010 in refs. [1 and 8] - BO3 triangles interconnected exclusively by corner-sharing. See other works in a 2012 paper and in a 2016 thesis. Data from the 2009 (766 models) and 2010 (5118 models) PCOD updates.

Not exhaustive list (more will be added during the next weeks, maybe)...
