Abstract

The reaction of 2 equiv. of [Os3(CO)10(MeCN)2] with R-C{triple bond, long}C-L-C{triple bond, long}C-R (R = H, L = (C4H2S); R = SiMe3, L = (C4H2S-C4H2S), (C4H2S-C4H2S-C4H2S), (C4H2S)-(C14H8)-(C4H2S)) affords the series of linked clusters [{Os3(CO)10}(HC{triple bond, long}C(C4H2S)C{triple bond, long}CH){Os3(CO)10}] (1), [{Os3(CO)10}(Me3SiC{triple bond, long}C(C4H2S-C4H2S)C{triple bond, long}CSiMe3){Os3(CO)10}] (2), [{Os3(CO)10}(Me3SiC{triple bond, long}C(C4H2S-C4H2S-C4H2S)C{triple bond, long}CSiMe3){Os3(CO)10}] (4) and [{Os3(CO)10}(Me3SiC{triple bond, long}C(C4H2S)-(C14H8)-(C4H2S)C{triple bond, long}CSiMe3){Os3(CO)10}] (6) as the major products. The complexes have been characterised by a range of spectroscopic methods and, in the case of 1 and 2 by single crystal X-ray crystallography. The alkyne groups cap the osmium triangles in the expected μ32-||-bonding mode and each triangle is coordinated by nine terminal and one μ2-carbonyl group. Solution UV-Vis spectra of the complexes were similar to those observed for the free ligands consistent with there being little delocalisation between the cluster units and the thiophene groups.
