Figure 3.

(A) Left: Thermal ellipsoid plot for 1a•Fp+ rendered at 50% probability level. Hydrogen atoms, noncoordinating PF6– counterion, and a THF solvent molecule are omitted for clarity. Selected metrical data for 1a•Fp+: d(Fe-P): 2.1809(4) Å, d(Fe-(CO)1): 1.7879(17) Å, d(Fe-(CO)2): 1.7893(16) Å, ∠(N1-P-N2): 93.42(6)⁰, ∠(N1-P-N3): 93.04(7)⁰, ∠(N2-P-N3): 116.39(7)⁰. Right: Schematic projection down the P–Fe axis for 1a•Fp+ illustrating dihedral angles φ(N-P-Fe-N). (B) Left: Thermal ellipsoid plot for 1b•Fp+ rendered at 50% probability level. Only one of two molecules in the asymmetric unit is depicted. Hydrogen atoms and a noncoordinating PF6– counterion are omitted for clarity. Selected metrical data for 1b•Fp+: d(Fe-P): 2.2381(5) Å, d(Fe-(CO)1): 1.7739(19) Å, d(Fe-(CO)2): 1.7792(18) Å, ∠(N1-P-N2): 101.59(8) ⁰, ∠(N1-P-N3): 105.03(9)⁰, ∠(N2-P-N3): 107.09(9)⁰. Right: Schematic projection down the P–Fe axis for 1b•Fp+ illustrating dihedral angles φ(N-P-Fe-N). See SI for full details.
