Synthesis and crystal structure of a novel compound constructed from tris-(2, 2 '-bipy)ruthenium(II) and decatungstate

Self-assembly of tris-[2,2 ' -bipyridine]ruthenium(II) chloride with decatu nstate produced a novel cation radical salt, [Ru(bpy)(3)](2)[W10O32] . 3DMS O. This is the first product of 2,2 ' -bipyridineruthenium(II)-polyoxometal ates species. Crystal data: Monoclinic, P2(1)/c, a = 12.902(3) Angstrom, b = 21.487(3) Angstrom, c = 15.854(5) Angstrom, beta = 93.46(2)degrees, V = 4 387(2) Angstrom (3), Z = 2, R-1 = 0.0599, wR2 = 0.1183. X-ray crystallograp hic study showed that the crystal structure was constructed by electyrostat ic attraction and C-H . . .O hydrogen bonds between tris-[2,2 ' -bipyridine ]ruthenium(II) and decatungstate polyanion. The tris-[2,2 ' -bipyridine]rut henium molecules occupy cavities in the polyoxometalate lattice ordered alo ng b-axis. (C) 2001 Elsevier Science B.V. All rights reserved.
