Abstract

Treatment of o-carborane, n-butyllithium, sulfur and Me₄CpCo(CO)I₂ under argon leads to half-sandwich 16e carborane complex Me₄CpCo[S₂C₂B₁₀H₁₀]. Me₄CpCo[S₂C₂B₁₀H₁₀] reacts with PPh₂Me, PPhMe₂, PMe₃ to afford addition products Me₄CpCo[S₂C₂B₁₀H₁₀](PPh₂Me) (I), Me₄CpCo-[S₂C₂B₁₀H₁₀](PPhMe₂) (II), Me₄CpCo[S₂C₂B₁₀H₁₀](PMe₃) (III), respectively. I, II and III have been characterized by IR, NMR, elemental analysis, mass spectrum. I and III have also been characterized by single-crystal X-ray diffraction analysis (CCDC nos. 2245287 (I) and 2245288 (III)). The UV and fluorescent spectra properties of the compounds I, II and III have been tested. The UV spectra results of complexes I, II and III in acetonitrile solution show that the bands are located at 412, 399 and 401 nm, respectively. The fluorescence spectra result of the complexes I, II and III exhibit maximum emission peaks at about 405 nm.
