Reactions between a carbide anion (C22- source and ruthenium cluster carbonyls are reported for the first time. The reaction between CaC2 and Ru3(CO)12, carried out in thf, affords putative Ca[Ru10(C)2(CO)24], which can be converted into [ppn]2[Ru10(C)2(CO)24] (1) in overall 60% yield. The X-ray structure of 1 as its 2CH2Cl2 solvate is described, together with those of the minor products Ru4(μ4-HC2H)2(μ-CO) 2(CO)9 (3), Ru6C(μ3-HC2Me)(CO)15 (4) and Ru4(μ4-CHCHCO)(μ-CO)(CO)10(tmeda) (5). The latter contains an Ru-spiked Ru3 core carrying a CHCHCO ligand; the tmeda chelates the spike Ru atom. The only product from Ru3(μ-dppm)(CO)10 and CaC2 is the known compound Ru6(μ4-CCH2)2(μ-dppm) 2(CO)12 (16), formed in 24% yield.
