Abstract

The temperature-dependent pmr spectrum of Rh(MePhdtc)3 was examined in CDC13 solvent over the temperature range —34° to +51°. The complex is stereochemically non-rigid and isomerizes by a C-N bond rotation mechanism. A line shape analysis yielded a value of ΔG‡= 61.5 ± 4.2 kJ mol-1. This barrier to rotation is large relative to similar complexes of Fe(II) and Fe(III) but similar to values for Fe(IV) and Co(III). Metal-centered optical inversion is slow over the temperature range studied.
