Comparison of the reactivity and spectroscopic data among the nitrido-bridged compounds and with related iridium(I) and rhodium(I) complexes suggests that the nitrido-bridged compounds are best viewed as adducts in which anionic [(R 3 SiO) 3 VN:] acts as a simple two-electron donor to the 14-electron cationic [M(L)(PPh) 2 ] + fragment

    NMR studies of intramolecular exchange in [(Ph3P)(3)Rh(X)] (X = CF3, CH3, H, Ph, Cl) have produced full sets of activation parameters for X = CH3 (E-a = 16.4 +/- 0.6 kcal mol(-1), Delta H-double dagger= 16.0 +/- 0.6 kcal mol(-1), and Delta S-double dagger = 12.7 +/- 2.5 eu), H (E-a = 10.7 +/- 0.2 kcal mol(-1), Delta H-double dagger = 10.3 +/- 0.2 kcal mol(-1), and Delta S double dagger = -7.2 +/- 0.8 eu), and Cl (E-a = 16.3 +/- 0.2 kcal mo1(-1), Delta H double dagger = 15.7 +/- 0.2 kcal mol(-1), and Delta S double dagger = 0.8 +/- 0.8 eu). Computational studies have shown that for strong trans influence ligands (X = H, Me, Ph, CF3), the rearrangement occurs via a near-trigonal transition state that is made more accessible by bulkier ligands and strongly donating X. The exceedingly fast exchange in novel [(Ph3P)(3)Rh(CF3)] (12.1 s(-1) at -100 degrees C) is due to strong electron donation from the CF3 ligand to Rh, as demonstrated by computed charge distributions. For weaker donors X, this transition state is insufficiently stabilized, and hence intramolecular exchange in [(Ph3P)(3)Rh(Cl)] proceeds via a different, spin-crossover mechanism involving triplet, distorted-tetrahedral [(Ph3P)(3)Rh(Cl)] as an intermediate. Simultaneous intermolecular exchange of [(Ph3P)(3)Rh(Cl)] with free PPh3 (THF) via a dissociative mechanism occurs exclusively from the sites cis to Cl (E-a = 19.0 +/- 0.3 kcal mol(-1), Delta H double dagger = 18.5 +/- 0.3 kcal mol(-1), and Delta S double dagger = 4.4 +/- 0.9 eu). Similar exchange processes are much slower for [(Ph3P)(3)Ir(Cl)] which has been found to exist in orange and red crystallographic forms isostructural with those of [(Ph3P)(3)Rh(Cl)].
