Reactions between Ru3(μ-H)μ3-SBut)(CO)9 and dppm have given Ru3(μ-H)(μn-SBut)(μ-dppm)(CO)10-n (n = 2, 3); hydrogenation of all three complexes resulted in S-C bond cleavage and formation of Ru3(μ-H)2(μ3-S)(CO)7(L2) .Facile substitution of 2CO in Ru3(μ-H)2(μ3-S)(CO)9 by dppm, dpam or ebdp (L2), catalysed by Na+anionradical or , gave Ru3(μ-H)2(μ3-S)(μ-L2)(CO)7, in which the bis-tertiary phosphine (or arsine) bridges on edge of the Ru3 triangle, with the P (or As) atoms occupying equatorial positions.In the case of L2 = ebdp, this edge is also bridged by H, as shown by a single-crystal X-ray structure determination.Crystals of the title compound are monoclinic, space group P21/n, with unit cell parameters a 13.454(3), b 17.748(2), c 14.706(2) Angstroem, and β 94.50(1) deg.The structure was refined by a full-matrix least-squares method; at convergence R and Rw were 0.036 and 0.038, respectively, for 4729 reflections with I 3.0?(I).
