%X Reactions between Ru3(&#956;-H)(&#956;3-SBut)(CO)9 and dppm have given Ru3(&#956;-H)(&#956;n- SBut)(&#956;-dppm)(CO)10-n(n = 2,3); hydrogenation of all three complexes resulted in S-C bond cleavage and formation of Ru3(&#956;-H)2(&#956;3-S)(CO)7(L2) [L2 = (CO)2, &#956;-dppm]. Facile substitution of 2CO in Ru3(&#956;-H)2(&#956;3-S)(CO)9 by dppm, dpam or ebdp (L2), catalysed by Na+[Ph2CO]- or [ppn][OAc], gave Ru3(&#956;-H)2(&#956;3-S)(&#956;-L2)(CO)7, in which the bis-tertiary phosphine (or arsine) bridges an 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 mcnoclinic, space group P21/n, with unit cell parameters a 13.454(3), b 17.748(2), c 14.706(2) &#506;, and &#946; 94.50(1)&#176;. 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 &#8805; 3.0&#963;(I).
