Fig. 3: Conformational analysis of compound 1.

A 31P NMR spectra of complex 1 in d2-DCM and d8-THF, revealing two conformers (1-exo and 1-endo). B Calculated structures of 1-endo and 1-exo (gas phase geometry shown). C Relative electronic energies of 1-exo and 1-endo in the gas phase, DCM, and THF (implicit solvation models; one explicit THF molecule included in THF-solvation calculations).
