SYNTHESIS AND X-RAY ANALYSIS OF AND

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.
