The title compound, [Ru(CHNO)(CHN)]PF crystallizes in the tetra-gonal Sohnke space group 422. The two bidentate chiral salicyloxazoline ligands and the phenanthroline co-ligand coordinate to the central Ru 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 PF 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.
标题化合物[Ru(CHNO)(CHN)]PF以四方Sohnke空间群422结晶。两个双齿手性水杨基恶唑啉配体和菲咯啉共配体通过N、O和N、N原子对与中心Ru原子配位,分别形成89.76 (15)°和79.0 (2)°的咬角。双齿配体的八面体配位导致螺旋桨状形状,这在配合物上诱导了以金属为中心的手性,具有右手(Δ)绝对构型[Flack参数值为-0.003 (14)]。配合物阳离子和无序的PF抗衡阴离子都位于二重旋转轴上。除了库仑力外,晶体凝聚还通过非经典的C-H⋯O和C-H⋯F相互作用得以确保。
