Planar boron rings were predicted some years ago by scientists studying gas‐phase boron clusters as building blocks for designing new molecular and solid‐state materials. In their Communication on page 13174 ff., B. P. T. Fokwa et al. report experiments and density functional calculations used in a synergistic manner for the discovery of the new ferromagnetic material, Nb 6 Fe 1− x Ir 6+ x B 8 ( T c =350 K), containing in its crystal structure iron chains embedded in stacked B 6 rings.
