Reactions between Ru₂(DMBA)₄(NO₃)₂ and OPEn-S-TMSE ligand under weak base conditions afford trans-Ru₂(DMBA)₄(OPEn-S-TMSE)₂ compounds, where DMBA is N,N′-dimethylbenzamidinate, TMSE is trimethylsilylethylene, and OPEn are –CCC₆H₄– (1), –CC(2,5-(CH₃O)₂C₆H₂)–(CCC₆H₄)– (2) and –(CCC₆H₄)–CC(2,5-(CH₃O)₂C₆H₂)–(CCC₆H₄)– (3). Molecular structures of compounds 1 and 2 were determined by X-ray diffraction, which revealed the extended rigid rod topology and coplanarity of phenyleneethynye units in 1 and 2. Electrochemical and optical energy gaps of compounds 1–3 were estimated to be 1.57 eV and ca. 1.43 eV, respectively, from voltammetric and absorption spectral measurements.
