%X The conformational analyses of the complexes [Co(CN)4L]-, [Co(NH3)4L]3+, [Mo(CO)4L], and [PtL2]2+, where L is (R)-1-phenylethane-1,2-diamine, have been carried out by a method based on the vicinal proton coupling constants of the CHCH2 fragment. In the three octahedral complexes, the phenyl showed a similar preference for the equatorial orientation with n&#955; values of 0.87±0.05, 0.84±0.11, and 0.77±0.01, respectively. For the bis(diamine)platinum(II) complex, the &#955;&#955; and &#948;&#955; configurations were found to be equally populated, with the &#948;&#948; configuration 3.4 kJ mol-1 less favoured.
