Abstract

The title compound, having the mol-ecular formula [RuI(η⁶-C₁₀H₁₄)(C₁₀H₈N₂)]PF₆, crystallizes in the triclinic P (Z = 2) space group as a half-sandwich complex resembling a three-legged piano stool. Important geometrical parameters include Ru-cymene centroid = 1.6902 (17) Å, Ru-I = 2.6958 (5) Å, [Ru-N]_avg = 2.072 (3) Å, N1-Ru-N2 = 76.86 (12)° and a dihedral angle between the planes of the two rings of the bipyridyl system of 5.9 (2)°. The PF₆ ^- ion was treated with a twofold disorder model, refining to a 65.0 (8):35.0 (8) occupancy ratio. The crystal packing features C-H⋯F/I inter-actions.
