This image was composed by rendering the crystal structures/simulations of the allotropes using VESTAS 3.4.6 (Momma, K. and Izumi, F. 2011. VESTA 3for three-dimensional visualization of crystal, volumetric and morphology data. Journal of Applied Crystallography 44(6), pp. 1272–1276. Available at: https://dx.doi.org/10.1107/S0021889811038970.) and exporting the images as SVG. The individual images were combined, edited and annotated using Atom 1.38.0.
