Abstract
The coordination environment around RuII is best described as pseudo-octahedral, resembling the familiar half-sandwich ‘three-legged piano-stool’ structure.
The title compound, [RuCl(C6H6)(C14H10N2)]BF4 or [Ru(η6-benzene)(L)Cl]+BF4− [where L denotes the 2-(pyridin-2-yl)quinoline ligand], crystallizes in the monoclinic space group P21/c. The coordination environment around RuII is best described as pseudo-octahedral, resembling the familiar half-sandwich ‘three-legged piano-stool’ shape. In the coordination sphere, the η6-binding benzene ligand coordinates with the central RuII atom occupying the ‘seat’ of the stool with a metal-to-centroid distance of 1.695 (17) Å, while the chelate ligand L coordinates with its N atoms and, together with the Cl ligand, defines the ‘legs’ of the stool. Apart from Coulombic forces, C—H⋯F and C—H⋯Cl hydrogen-bonding interactions consolidate the crystal packing.
