In 2013, Prasad et al. reported a new hypothetical carbon allotrope called "squaroglitter" with C 8 stoichiometry. The designation as "-glitter" is due to the presence of sp 2 carbon (in addition to the tetrahedral sp 3 carbon) in the structure, which shows similarity to the previously announced C 6 "glitter" . Both carbon allotropes are electrically conductive due to the presence of sp 2 carbon. C 8 "squaroglitter"' belongs to the chromium boride (crb) topology, which is a large family of carbon allotropes presented in the SACADA database . The crb topology archetype is identified as SACADA ID 60; the structure is shown in Fig. . The polyhedral representation on the right shows a characteristic central square of sp 3 carbons bonded to form 2×2 edge-sharing tetrahedra that are corner-sharing along the c-axis. The crystal structure belongs to space group I4/mmm (No. 139) (Table ), with all eight carbon atoms occupying a single Wyckoff position, namely (8h).
