Аннотация:Electronic spectra and redox potentials of new mixed-valence Rh-1-Rh-111 complexes linked by a cyanide bridge were measured and studied. For these compounds, interaction between rhodium atoms in the molecule is low (a case of ''fixed valences''), and no intervalence transition from Rh-1 to Rh-111 was observed in the 7000 to 50000 cm(-1) range. Some of the complexes in the solid state have additional absorption bands in the diffuse reflectance spectra related to the interaction of orbitals (with appropriate symmetry) of Rh(1) fragments of adjacent complex molecules.
