Adsorption ofin situoxidized ruthenium complexes on sodium montmorillonite (Na-Mt) was examined using two approaches (methods A and B) in order to establish a versatile method for stabilizing oxidized compounds. [Ru(acac)3]+(1-Ru+) and [Ru(acac)2(hino)]+(2-Ru+, Hhino = hinokitiol), which were each prepared byin situoxidation of1-Ruand2-Ruwith ammonium cerium(IV) nitrate (CAN), were used as models of oxidized compounds. In method A, an acetonitrile solution containing oxidized ruthenium complexes was added to an aqueous colloidal solution of Na-Mt, followed by filtering and air drying. In method B, an acetonitrile solution containing the oxidized complexes was drop-casted on powders of Na-Mt, followed by grinding and air drying.1-Ru+was hardly adsorbed onMtin both methods, probably owing to the short lifetime of1-Ru+in solution. In contrast,2-Ru+was adsorbed onMtwhen method B was applied. X-ray diffraction analysis indicated that2-Ru+existed not only in the interlayer space but also on the surfaces or edges of theMtparticles. The2-Ru+complexes in the cast sample, including non-intercalated ones, were stable at least for a week according to Raman spectroscopy, whereas2-Ru+withoutMtreturned to2-Ruwithin a day in the solid state. The formation of a “house-of-cards”-like structure ofMtparticles is proposed to be one reason why non-intercalated2-Ru+complexes are stabilized in the cast sample.
