摘要：

Reaction of the labile triosmium cluster [Os-3(CO)(10)(NCMe)(2)] with the thienyl substituted diyne [(C4H3S)C2C2(C4H3S)] affords [Os-3(CO)(10){mu (3)-eta (2)-(C4H3S)C2C2(C4H3S)}] 1 and the novel co-linear cluster [Os-3(CO)(11){mu (3)-eta (4)-(C4H3S)C2C2(C4H3S)}] 2 in reasonable yield; the X-ray structure of 2 shows that the diyne is coordinated to an 'open' triosmium unit as a 1,2,3-triene-1,4-diyl unit with essentially equal C=C bond distances.
