Reaction of RuCl2(PPh3)3 with Ppy3 (py = 2-pyridyl) in benzene produced the N,N′,N″-Ppy3 complex RuCl2(PPh3)(PPy3) 1. Crystals of RuCl2(PPh3)(Ppy3). 2CH2Cl2(C35H31Cl6N 3P2Ru) are monoclinic, a = 17.269(2), b = 10.797(1), c = 20.604(1) A, β = 107.461(6)°, Z = 4, space group P21/c. The structure was solved by the Patterson method and was refined by full-matrix least-squares procedures to R = 0.039 and Rw = 0.035 for 4184 reflections with I ≥ 3σ(I). Complex 1 reacts in MeOH or benzene with two-electron donors (L) to give the chloride-substituted, [RuCl(L)(PPh3)(Ppy3)]PF6, or the triphenyl-phosphine-substituted products, RuCl2(L)(Ppy3), (L = CO, MeCN, PhCN), respectively. [RuCl(MeOH)(PPh3)(Ppy3)]BPh4 was also isolated. The non-coordinated phosphorus atom in 1 was oxidized to form RuCl2(PPh3)(OPpy3).
