A Bis(pyrazolyl) (bipyridyl) Platinum Complex

Abstract

Bis(3,5-dimethylpyrazolium)4,4'-dimethyl-2,2'-bipyridyl) platinum (II).O.5 tetrahydrofuran solvate-.H2O, PtC24H32N601.5, M (r) = 623.65; monoclinic, P2(1)/n; a = 8.625(2), beta = 20.593(8), c = 14.451(4) A, Beta = 90. 32(2) deg, V = 2566.7(14) A3, Z = 4, D (x), = 1.61 g cm-3, MoK alpha, 0.71073 A, mu = 55.50 cm-1, F(OOO) = 1232, room temperature, R = 0.0387 for 2874 reflections with F(2) sub omicron > 3 Signa (F(2) sub omicron. The square-planar Pt complex has normal Pt-N(bipyridyl) bonds (2.009(8) A) and slightly short Pt- N(pyrazolyl) bonds (1.983(7) A). The ligand molecules have normal distances and angles; the planes of the pyrazolyl ligands are twisted by about 60 deg to the bipyridyl-Pt plane, with the closest contacts between the pyrazolyls being approx. 3.3 A (Cl4 ... N5 and C19...N3).
