Chemical Structure from Scientific Research

HOMO (top row) and second MO (bottom row) under consideration for compounds 5. For open-shell compounds, the respective orbital is depicted. Hydrogen atoms are omitted for clarity. Gray: C, beige: Si, light blue: Y, grey blue: Sb, orange: Bi, green: Er, dark blue: Tb. Note that compared to Figs. 3b and 5b the molecules are rotated counterclockwise around the CtCOT Ln-CtSb/Bi axis by 90.
