Abstract: Thiopheneacetylene (RC6-point triple bond; length half of m-dashCH; R=3-Th, 2-Th; Th=C4H3S) adds across the Se–Se bond of (CO)6Fe2(μ-Se2) at room temperature in methanol solvent containing sodium acetate to yield the adduct (CO)6Fe2{μ-SeC(H)=C(R)Se} (R=3-Th (1); 2-Th (3)) and the double butterfly complex [{(CO)6Fe2Se2}2{μ-C(H)–C(R)}] (R=3-Th (2); 2-Th (4)). Compounds 1–4 were characterized by spectroscopic techniques (IR and 1H-, 13C- and 77Se-NMR) and their composition confirmed by elemental analysis. Structures of 2 and 4 were further confirmed by single-crystal X-ray diffraction study.
