No full textThe reaction of Pt(IPr)(SnBu 3 t )(H), 1 [IPr = N-heterocylic carbene ligand N,N ′-bis-(2,6-(diisopropyl) phenyl)imidazol-2-ylidene] with Ru5(μ 5 -C)(CO)15, 2, in 1.2:1 (and 2.2:1) ratio in benzene solvent at refluxing temperature afforded the octahedral monoplatinum–pentaruthenium cluster complexes PtRu5(IPr)(CO)15(μ 6 -C), 3 in 54 % (10 %) yield, PtRu5(IPr)(CO)14(H)2(μ 6 -C), 4 in 6 % (10 %) yield and the diplatinum–pentaruthenium cluster complex Pt2Ru5(IPr)2(CO)15(μ 6 -C), 5 in 2 % (36 %)yield. Complex 3 readily reacts with H2 at room temperature to give complex 4. Compound 5 exhibits dynamical activity in solution where the two Pt(IPr) groups are exchanging rapidly. All three compounds were structurally characterized by single-crystal X-ray diffraction analyses
