Extended Data Fig. 5: Ellipsoid plots of the nuclear quadrupole moment tensor.
Visualization of the quadrupole tensors arising from the Ln nucleus computed with DFT for compounds 4 (a), 3 (b), and 2 (c). Because η is small, the ellipsoids are effectively spheroidal in all three cases. Scaling factors, s, of 5.5 × 103, 5.5 × 103, and 1.65 × 104 were applied in (a), (b), and (c), respectively; see Supplementary Information Section 5 for further details. Hydrogen atoms were omitted for clarity. Color codes: Grey = C, Red = O, Tan = Si, Blue = N, Teal = Ln.
