Bis(ligand)ruthenium(II) complexes [ligand = tris(2-pyridyl)amine, tris(2-pyridyl)methane, and tris(2-pyridyl)phosphine] were synthesized by the reaction of [Ru(DMF)6]2+ (DMF = N,N-dimethylformamide) with excess of the respective ligands under anaerobic conditions in propan-1-ol solution. Crystals of [Ru{(2-Py)3CH}2](tosylate)2·H 2O (1) crystallize in the monoclinic space group C2/c with unit cell dimensions a = 13.205 (9) A?, b = 13.437 (6) A?, c = 23.614 (22) A?, β = 96.57 (6)°, V = 4162.5 A?3, and Z = 4; crystals of [Ru{(2-py)3P}2](tosylate)2·C 2H5OH (2) are also monoclinic (P21/c) with a = 10.065 (7) A?, b = 13.008 (4) A?, c = 34.772 (22) A?, β = 92.40 (5)°, V = 4548.6 A?3, and Z = 4. [Ru{(2-py)3N}2](S2O6)·4H 2O (3) crystallizes in the triclinic space group P1 with a = 8.914(3) A?, b = 9.060 (2) A?, c = 11.243 (2) A?, α = 95.52 (1)°, α = 104.19 (2)°, γ = 92.03(2)°, V = 874.6 A?3, and Z = 1. The structures were refined by a full-matrix least-squares procedure in each case. At convergence, final R = 0.050, Rw = 0.055 for 2931 reflections with I ≥ 2.5σ(I) for 1, R = 0.063, Rw = 0.065 for 2017 reflections for 2, R = 0.039, Rw = 0.041 for 2582 reflections for 3. The cations show increasing distortion in the structure from ideal D3d symmetry with an increase in the bridgehead (X)-C(py) bond distance.
