The Preparation of Bis(2,2'-bipyridtne)-and Bis(l, 10-phenanthroline)-carbonatoruthenium(II) Complexes

Abstract

Bis(2,2'-bipyridine)-and bis(l, 10-phenanthroline)carbonatoruthenium(II)complexes were synthesized by refluxing the corresponding dichloro complex in water with traces of formic acid, and passing the solution through an anion exchange column of carbonate form in order to remove chloride ions and to form the desired complex. Both complexes were dark violet, and diamagnetic. Electronic spectra of the complexes in dichloromethane and absorption curves of their crystalline powders were measured. The complexes were found to be nonelectrolytes in dichloromethane. The IR data indicated that the carbonate group in the complexes is coordinated to a ruthenium as a bidentate ligand. © 1979, The Chemical Society of Japan. All rights reserved.
