    • At least some of the splitting in the dπ manifold may be due to interactions with the acac LUMOs, which are calculated to be much closer in energy to the dπ orbitals than the acac HOMOs (ΔE ≈ 1.3 and 4 eV, respectively). Since the nodal pattern of the acac LUMO is reversed relative to the HOMO, the effects are synergistic in the A manifold, with the higher dπ orbital interacting only with the filled acac orbital and the lower-energy dπ orbital interacting only with the empty acac orbital. More details on the calculations are given in the Supporting Information.

    • 13C satellites of the major compound, so 100:1 is a conservative estimate of the preponderance of the major diastereomer. More modest lower limits on the dr must be given for the progressively less soluble dbm and acac complexes; the latter also exists in a monomer/dimer equilibrium.

    • 2Sn(BINOL) (where both diastereomers can be observed) confirms that the methyl groups in the minor diastereomer exchange with the axial and equatorial methyl groups in the major diastereomer at comparable rates.
