Figure 5
Unit cell along the (a) a and (b) c directions. Grey lines highlight the triangular-hexagonal Fe1/Fe3/Fe5/Fe6 layers with Fe4 in between and the Fe2 coordination. Green trigonal prisms show coordination of B. (c)–(k) Coordination environments of all symmetry-independent atoms visualized along the a direction. Thin grey lines show the first coordination sphere (within 3.8 Å), black lines show bonding contacts confirmed by the presence of BCPs at 25 K. The 300 K structure is used for visualization with thermal ellipsoids shown at a 99% probability level. Figures were drawn using Vesta (Momma & Izumi, 2008View full citation).
