抄録

Various cationic rhenium(I) and ruthenium(II) mono- and multinuclear complexes were successfully separated by size-exclusion chromatography (SEC), using a 50:50 (v/v) mixture of methanol and acetonitrile with CH<sub>3</sub>CO<sub>2</sub>NH<sub>4</sub> as an eluent. The logarithms of the molecular weights were accurately linear in the distribution coefficients: for linear-shaped rhenium(I) multinuclear complexes, log <i>M</i><sub>W</sub> = -2.86<i>K</i><sub>SEC</sub> + 5.24 (<i>r</i> = -0.990 and <i>n</i> = 15); for ring-shaped rhenium(I) multinuclear complexes, log <i>M</i><sub>W</sub> = -2.94<i>K</i><sub>SEC</sub> + 5.40 (<i>r</i> = -0.999; <i>n</i> = 5); for bimetallic complexes including ruthenium(II), log <i>M</i><sub>W</sub> = -0.40<i>K</i><sub>SEC</sub> + 3.37 (<i>r</i> = -0.959; <i>n</i> = 6). This separation method is applicable to the preparative-scale separation of cationic multinuclear complexes from a mixture.
