a Plot of the tpa-Δ in [Me3tpa] (squares, dashed lines) and [Me2tpa] (circles, solid lines) at variable temperature and pressure. Values for both symmetry-independent complexes, A (light blue) and B (dark blue) is given. A diagram of the triangular area, the tpa-Δ, in the tpa complexes, with vertices on the methyl-bearing carbon atom, is overlaid. Vertical error bars are calculated from the estimated standard deviations on tpa-Δ from the crystal structures. b Plot of relative spin-state energy (ΔE) vs applied stimuli, for [Me2tpa] (circles) and [Me3tpa] (squares) for each symmetry-independent molecule, A (light blue) and B (dark blue).
