Back Cover: Unexpected Synergy between Magnetic Iron Chains and Stacked B6 Rings in Nb6Fe1−xIr6+xB8 (Angew. Chem. Int. Ed. 48/2014)
Graphical Abstract
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, Nb6Fe1−xIr6+xB8 (Tc=350 K), containing in its crystal structure iron chains embedded in stacked B6 rings.
