Abstract

Reaction of K2[RuCl5(H2O)] with 1,4,7,10-tetramethyl-1,4,7,10-tetra-azacyclotridecane(L) in ethanol yielded cis-[RuLCl2]ClO4. The optical spectrum shows an intense pπ(Cl) → dπ(Ru) charge-transfer transition at 378 nm. The cis-[RuLCl2]+ cation [space group P21/n, a = 12.388(2), b = 12.740(2), c = 12.853(4) Å, β = 96.68(2)°, Z = 4; R = 0.048 for 1 897 observed Mo-Kα data] is distorted octahedral with two Ru-Cl bonds cis to each other. The measured Ru-Cl distances [2.406(3) and 2.370(4) Å] are unusually long for a ruthenium(III) system.
