N2 - The hydrido-nitrosyl cluster [Ru3(CO)10H(NO)] has been prepared in high yield from the reaction of Na[Ru3(CO)11H] with [NO][PF6]. The corresponding osmium complex, [Os3(CO)10H(NO)], has been prepared in lower yield from Na[Os3(CO)11H]. The complex [Ru3(CO)10H(NO)] reacts with P(OMe)3 to produce the trisubstituted complex [Ru3(CO)7H(NO){P(OMe)3}3], which crystallises in the monoclinic space group P21/c with cell dimensions a = 14.666(4), b = 12.743(4), c = 18.384(7) Å, β = 112.57(3)°, and Z = 4. The structure has been solved by a combination of multisolution sigma-2 sign-expansion and Fourier techniques, and refined by full-matrix least squares to R 0.052 for 4 547 unique observed intensities. The three ruthenium atoms define an isosceles triangle, the shortest edge of which is symmetrically bridged by both a nitrosyl and a hydrido-ligand. The complex [Ru3(CO)10H(NO)] reacts with PPh3 to give the three related complexes [Ru3(CO)10-nH(NO)(PPh3)n] (n = 1-3).
