Δ-Bis[(S)-2-(4-isopropyl-4,5-di-hydro-oxazol-2-yl)phenolato-κ2 N,O 1](1,10-phenanthroline-κ2 N,N')ruthenium(III) hexa-fluorido-phosphate.

Abstract

The title compound, [Ru(C12H14NO2)2(C12H8N2)]PF6 crystallizes in the tetra-gonal Sohnke space group P41212. The two bidentate chiral salicyloxazoline ligands and the phenanthroline co-ligand coordinate to the central RuIII atom through N,O and N,N atom pairs to form bite angles of 89.76 (15) and 79.0 (2)°, respectively. The octa-hedral coordination of the bidentate ligands leads to a propeller-like shape, which induces metal-centered chirality onto the complex, with a right-handed (Δ) absolute configuration [the Flack parameter value is -0.003 (14)]. Both the complex cation and the disordered PF6 - counter-anion are located on twofold rotation axes. Apart from Coulombic forces, the crystal cohesion is ensured by non-classical C-H⋯O and C-H⋯F inter-actions.
