Figure 3.
a) G95, a predicted carbon allotrope that combines structural motifs from diamond (dia), lonsdaleite (lon), and „M‐carbon“ (cbn), as revealed by topology analysis. b) Predicted carbon allotropes with „5+5+8“ building blocks. Cages that involve an eight‐membered ring, typically [52.62.82], are highlighted in yellow; [52.62] cages are blue. Interestingly, the apparent end‐member of this series, G105, is different in cage topology from the others, and filling space exclusively with [52.62.82] and [52.62] cages would yield the bik network instead (Supporting Information). All energies are given relative to diamond.
