摘要：

Radiation reduction of binuclear [Rh-2(OAc)(2)(phen)(2)(H2O)(2)](OAc)(2), [Rh-2(OAc)(tpy)(2)Cl-2]Cl . 2H(2)O and [Rh2Cl2(HCOO)(2)(bpy)(2)]. 4H(2)O complexes in aqueous-methanol solution have been studied. The reduction yields as equal to ca. 6 equiv/100 eV and the rate constants of reactions: complex+e(solv)(-) as equal to 2.9.10(10), 3.2.10(10) and 3.7.10(10) M-1.s(-1), respectively, have been determined. On the basis of electronic spectra it has been shown that Rh(II) compounds were reduced giving several Rh(I) complexes being in equilibrium. The mechanism of the processes has been discussed.
