ReCl3(RCN) (PR′3) complexes (R = Me, Et, Ph ;′ = Ph, p-tol, m-tol) give relatively narrow 1H NMR signals in spite of the presence of the paramagnetic Re(III) centre. The signals of one ligand are not greatly affected by changes in the other ligand. In all cases, the spectra are consistent with the met-trans structure previously foundin the solid state for ReCl3(MeCN) (PPh3)2. for P(m-tol)3, the preparation
