Synthesis, redox properties, and electronic characteristics of complexes {Cp*(dppe)FeC≡CC2R[Mo2Cp2(CO)4]} n+

New acetylene-bridged complexes {Cp*(dppe)FeC≡CC2R[Mo2Cp2(CO)4]} n+ (R = H, SiMe3; n = 0, 1, 2) containing the mononuclear organoiron and cluster (Mo2C2) fragments were synthesized and their electrochemical and spectroscopic properties were studied. NearIR spectroscopy showed that single-electron oxidation results in the formation of compounds with electronic communication between two metal centers. The conductivity parameters were estimated suggesting the compounds obtained to be molecular conductors of class II according to the Robin-Day classification.
