The reaction of with (C8H12=cyclo-octa-1,5-diene) results in the formation of (1).The geometry of (1) may be derived from that of by bridging one edge of the central Os tetrahedron with one Pt atom of the dimer unit Pt2(μ-C8H10)(C8H12).One C8H12 group has been dehydrogenated to C8H10 and the two resulting hydride ligands are terminally bound to different metals of the Os6 core.The C8H10 ligand is bound in an η3-allyl fashion to one Pt atom and by an η2-olefinic bond and ?-alkyl bond to the second Pt atom.Upon heating in toluene, complex (1) rearranges to the known complex (3).Complex (3) is without hydride ligands and possesses a geometry of two edge-fused Os tetrahedra, one of which is Pt-bicapped.The complex (2) was isolated from the reaction of with C8H12.Complex (2) has the bicapped tetrahedral geometry of with the μ-C8H11 group bridging two Os atoms of the central tetrahedron.The hydride ligand caps a triangulated Os face.This complex reacts with CO to afford the parent cluster .

The cluster anion -(1) has been obtained from the reaction of in BuiOH and X-ray analysis of its + salt shows that the anion has an unusual fused tetrahedral metal-core geometry related to that of .Reaction of (1) with iodine gives (2) in which an overall change in cluster geometry has occurred; the reaction is reversible and heating (2) with iodide regenerates (1).Reaction of (1) with concentrated H2SO4 gives which reacts with P(OMe)3 to give > and with halide ions to give evantually 2-.Crystals of are triclinic, space group P, with a = 16.775(3), b = 13.509(2), c = 11.267(2) Angstroem, α = 89.88(1), β = 103.97(1), γ = 96.99(1)deg, and Z = 2.Refinement of atomic parameters using 5 615 absorption-corrected data converged at R = 0.0359.Crystals of *H2O are monoclinic, space group P21/c, with a = 14.386(2), b = 11.037(1), c = 24.629(3) Angstroem, β = 94.30(2)deg, and Z = 4.Refinement of atomic parameters using 4 644 absorptioncorrected reflections converged at R = 0.0569.
