摘要：

(4,4'-Dimethyl-2,2'-bipyridyl)bis(3,5-di-methylpyrazolium)platinum(II) 0.5-tetrahydrofuran solvate monohydrate, [Pt(C5H7N2)2(C12H12-N2)].0.5C5HgO.H2O, M(r) = 623.65, monoclinic, P2(1)/n, a = 8.625 (2), b = 20.593 (8), c = 14.451 (4) angstrom, beta = 90.32 (2)-degrees, V = 2566.7 (14) angstrom3, Z = 4, D(x) = 1.61 g cm-3, lambda(Mo Kalpha) = 0.71073 angstrom, mu = 55.50 cm -1, F(000) = 1232, room temperature, R = 0.0387 for 2874 reflections with F-0(2) > 3sigma(F-0(2)). The square-planar Pt complex has normal Pt-N(bipyridyl) bonds [2.009 (8) angstrom1 and slightly short Pt-N(pyrazolyl) bonds [1.983 (7) angstrom]. The ligand molecules have normal distances and angles; the planes of the pyrazolyl-ligands are twisted by about 60-degrees to the bipyridyl-Pt plane, with the closest contacts between the pyrazolyls being approximately 3.3 angstrom (C14...N5 and C19...N3).
