Two distinct types of such [Rh₂O₁₀] units, B1 and B2/B3 (see text), are found experimentally³³. Results of spin-orbit MRCI calculations are shown, with a local coordinate frame for each Rh-Rh link (x along the Rh-Rh bond, z perpendicular to the Rh₂O₂ plaquette). The form of the actual lattice spin model is detailed in the SM.

¹ Inline graphic (Rh-O-Rh)=93.4°, d(Rh-Rh)=2.95 (×2), d(Rh-O_1,2)=2.03 Å.

² Inline graphic (Rh-O-Rh)=94.1°, d(Rh-Rh)=2.95 (×4), d(Rh-O₁)=2.03, d(Rh-O₂)=2.00 Å. O₁ and O₂ are the two bridging O’s.
