%X The crystal and molecular structures of Ru4(&#181;-H)4(CO)11(CNBut) (2), obtained with Ru4(&#181;- H)4(CO)10(CNBut)2 by hydrogenation of Ru5(&#181;5-CNBut)(CO)14(CNBut) (1), have been determined. Crystals of (2) are monoclinic, space group P 21/c, with a 12&#183;349(1), b 11&#183;627(3), c 17&#183;0222(7) &#197;, &#946; 105&#183;785(4)&#176;, V 2351&#183;9(6) &#197;3 and Z 4. The structure was solved by direct methods and refined using 4478 reflections to final R 0&#183;028(Rw0&#183;033). An improved procedure for the preparation of (1) in 35&#8211;40% yields is also described.
