Terthiophenes bearing pendant organomolybdenum complexes, erythro-[Mo2 (η-C5H5) 2 (CO) 4 {µ-η2∶ η2-C (R) C [C4HS (C4H3S-2) 2-2, 5]}(R= H 1a or Ph 1b) were prepared by reaction of [Mo2 (η-C5H5) 2 (CO) 4] with 3′-alkynyl-2, 2′∶ 5′, 2 ″-terthiophenes. The molecular structures of 1a and 1b were identified by spectroscopic methods and X-ray diffraction. Cyclic voltammetry of 1a and 1b showed deposition of electroactive polymeric ...
