Abstract

The magnitude and sign of ¹H-³¹P and ¹H-¹³C coupling constants across the central metal atom (²J_X-Rh-H) were measured in a series of octahedral rhodium hydrido phosphine complexes [Rh(PMe₃)₂(CO)(Cl)(X)H; X = Cl, phenyl (2 isomers)] using a ¹H detected, frequency-selective, two-dimensional NMR experiment. The relative and absolute signs of ²J_13C-Rh-H, ²J_13C-Rh-P, and ²J_P-Rh-H were determined, and in the case of ²J_13C-Rh-H both the magnitude and sign of the coupling constant were found to depend on the relative disposition of the coupled nuclei about the central metal atom.
