The alkynes HC{triple bond}CCMe{sub 2}NHCOR react with M{sub 3}(CO){sub 12} (M = Ru or Os) giving, upon oxidative addition, the expected hydrides ({mu}-H)M{sub 3}(CO){sub 9}({mu}{sub 3}-{eta}{sup 2}-C{triple bond}CCMe{sub 2}NHCOR) and the unprecedented butterfly clusters M{sub 4}(CO){sub 11}({mu}{sub 4}-{eta}{sup 2}-HC{triple bond}CCME{sub 2}NHCOR). These complexes have been characterized by spectroscopic studies; the structure of the ruthenium butterfly cluster with R = C{sub 6}H{sub 9} has been determined by X-ray diffraction methods. Crystals, containing CHCl{sub 3} as solvation molecules, are triclinic with Z = 2 in a unit cell of dimensions a = 13.521 (6), b = 14.617 (6), c = 9.049 (5) {angstrom}, {alpha} = 79.28 (2), {beta} = 108.79 (2), {gamma} = 111.85 (2){degree}.
