%X The molecular structures M3(&#956;3-&#951;2-PhC2C&#8801;CPh)(&#956;-CO)(CO)9 (M = Ru and Os) are described: these complexes are similar to several mono-alkyne derivatives, with one C&#8801;C triple bond of the diyne ligand attached in the 2&#951;1,&#951;2-(||) mode to the closed triangular M3 core. The M-M edge parallel to the complexed C&#8801;C triple bond is asymmetrically bridged by a CO ligand; the coordination about each M atom is completed by three terminal CO ligands. Crystals of the isomorphous Os [ Ru ] complexes were triclinic, space group P&#299; (Ci1, No. 2), a 18.869(9) [18.881(5)], b 9.164(3) [9.188(3)], c 8.548(2) [8.595(6)] &#506;, &#945; 65.73(2) [66.00(3)], &#946; 78.53(3) [78.43(4)], &#947; 87.25(3) [87.58(2)]&#176;, Z 2. 7323 [3638] observed data [I > 3&#963;(I)] were refined to R 0.031 [0.030] and Rw 0.036 [0.032].
