Synthesis and characterization of the polyoxoanion-supported Ru[sup I]-Ru[sup I] tetracarbonyls [(P[sub 3]O[sub 9])[sub 2]Ru[sub 2](CO)[sub 4]][sup 4[minus]] and [Cp[sup *]TiW[sub 5]O[sub 18][sub 2]Ru[sub 2](CO)[sub 4]][sup 4[minus]]

Five new Ru[sub I]-Ru[sup I] tetracarbonyl complexes, including two incorporating polyoxoanion ligands, have been prepared: [(P[sub 3]O[sub 9])[sub 2]Ru[sub 2](CO)[sub 4]][sup 4[minus]] (1), [(Cp[sup *]TiW[sub 5]O[sub 18])[sub 2]Ru[sub 2](CO)[sub 4]][sup 4[minus]] (2), [(CH[sub 3]CN)[sub 6]Ru[sub 2](CO)[sub 4]][sup 2+] (3), [(PPh[sub 3])[sub 2](CH[sub 3]CN)[sub 4]Ru[sub 2]-(CO)[sub 4]][sup 2+] (4), and [(C[sub 5]H[sub 5]N)[sub 6]Ru(CO)[sub 4]][sup 2+] (5). Two of these complexes were structurally characterized in the solid state using single-crystal X-ray diffraction techniques: complex 1 as a solvated tetra-n-butylammonium salt [[(P[sub 3]O[sub 9])[sub 2]Ru[sub 2](CO)[sub 4]](TBA)[sub 4][center dot]2CH[sub 3]CN: a = 11.737(1) [angstrom], b = 16.166(3) [angstrom], c = 24.583(7) [angstrom], [beta] = 100.19(2)[degrees], Z = 2, space group P2[sub 1]/c-C[sup 5][sub 2h]] and complex 4 as a hexafluorophosphate salt [[(PPh[sub 3])[sub 2](CH[sub 3]CN)[sub 4]Ru[sub 2](CO)[sub 4]](PF[sub 6])[sub 2]: a = 29.157(5) [angstrom], b = 9.341(2) [angstrom], c = 20.673(3) [angstrom], [beta] = 108.40(5)[degrees], Z = 4, space group C2/c-C[sup 6][sub 2h]]. The remaining were formulated and assigned structures on the basis of their elemental compositions. NMR spectra, and infrared spectra. Complex 3 proved to be a reactive precursor to a variety of Ru[sup I]-Ru[sup I] tetracarbonyl complexes, including complexes 1, 2, 4, and 5.
