Abstract

The molecular structures of four ruthenium cluster complexes, isolated in small amounts in the course of studies of the reactions of alkynes or a 1,3-diyne with ruthenium cluster carbonyls, are reported: Ru33-PhC2C=CHPh)(µ- OH)(CO)9 (1), from Ru3(CO)10(NCMe)2and PhCÅflCCÅflCPh, is probably formed by addition of water to a diyne– Ru3 precursor; Ru33-C(OCH2CH=CH2)CHCCPh2OC(O)}(µ-dppm)(µ-CO)(CO)6 (2) was isolated from the many products of the reaction between Ru3(µ−dppm)(CO)10and HCÅflCCPh2(OH); Ru4(µ4-PhCHC2CHPh)(CO)12 (3) was found among the thermolysis products of Co2Ru3(µ5-PhC2C2Ph)(µ-CO)3(CO)11; and Ru44-CHCCH2- CHPMe3)(CO)10(PMe3) (4) was formed by reaction of PMe3 with Ru3(µ3-HC2H)(µ-CO)(CO)9.
