Abstract

Two heterometallic compounds [WRu3L(CO)11(µ-H)2(AuPPh3)](L = C5H51 or C5Me52) were prepared by hydrogenation of [WRu3L(CO)12(AuPPh3)] in refluxing tetrahydrofuran solution. The C5H5 derivative possesses a tetrahedral Ru3W core in which the AuPPh3 unit bridges a Ru–Ru edge, one hydride caps a nearby WRu2 face and the second spans a Ru–Ru edge, whereas the corresponding C5Me5 derivative adopts a related but distinct molecular geometry in the solid state, in which both hydride ligands span the equivalent Ru–W edges and the AuPPh3 unit is linked to the Ru atoms supporting the hydrides. The dynamic processes in solution were established for these two derivatives. Crystal data for 1: monoclinic, space group P21/c; a= 9.031(2), b= 25.086(4), c= 16.238(3)Å, β= 95.75(2)°, Z= 4; final R= 0.036, R′= 0.032 for 4391 reflections with l > 2σ(l). Crystal data for 2: space group Pna21; a= 20.389(3), b= 16.226(3), c= 26.074(4)Å, Z= 8; final R= 0.040, R′= 0.036 for 4556 reflections with l > 2σ(I).
