The title compound is an example for a chiral-at-metal complex, with the RuIII atom having an octahedral coordination environment by three bidentate ligands.
The title compound, [Ru(C12H14NO2)2(C12H8N2)]PF6 crystallizes in the tetragonal 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 octahedral 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 interactions.

A new triazole-based N-heterocyclic carbene cationic iridium(I) complex with a tetrafluoridoborate counter-anion and hemi-solvating dichloromethane, [Ir(C8H12)(C18H15P)(C8H15N3)][BF4]·0.5CH2Cl2, has been structurally characterized.
A new triazole-based N-heterocyclic carbene IrI cationic complex with a tetrafluoridoborate counter-anion and hemi-solvating dichloromethane, [Ir(C8H12)(C8H15N3)(C18H15P)]BF4·0.5CH2Cl2, has been synthesized and structurally characterized. There are two independent ion pairs in the asymmetric unit and one dichloromethane solvent molecule per two ion pairs. The cationic complex exhibits a distorted square-planar conformation around the IrI atom, formed by a bidentate cycloocta-1,5,diene (COD) ligand, a triphenylphosphane ligand, and an N-heterocyclic carbene (NHC). There are several close non-standard H⋯F hydrogen-bonding interactions that orient the tetrafluoridoborate anions with respect to the IrI complex molecules. The complex shows promising catalytic activity in transfer hydrogenation reactions. The structure was refined as a non-merohedral twin, and one of the COD molecules is statistically disordered.

The solid-state structural analysis of the title compound reveals that the two molecules of bis(1-benzyl-3-mesitylimidazol-2-ylidene)silver are connected via a bridging chloride atom. The structure also reveals non-classical intermolecular hydrogen-bonding interactions involving the chloride counter-anion.
The title compound, [Ag2(C19H20N2)4]Cl·0.5C2H4Cl2, can be readily generated by treatment of (1-benzyl-3-(2,4,6-trimethylphenyl)imidazolium chloride with sodium bis(trimethylsilyl)amide followed by silver chloride. The molecular structure of the compound was confirmed using NMR spectroscopy and single-crystal X-ray diffraction analysis. The crystal structure of the title compound at 110 K has monoclinic (P21/c) symmetry. The represented silver compound is of interest with respect to antibacterial properties and the structure displays a series of weak intermolecular hydrogen-bonding interactions with the chloride counter-anion.

The title structure is made up of diperiodic anionic CuICN networks and two independent CuII complexes that are not covalently bonded to the networks.
The title structure, {[Cu(C4H11NO)3][Cu4(CN)6]·[Cu(C4H10NO)2(H2O)]·H2O}n, is made up of diperiodic honeycomb CuICN networks built from [Cu4(CN)6]2− units, together with two independent CuII complexes: six-coordinate [Cu(CH3CH2CH(NH2)CH2OH)3]2+ cations, and five-coordinate [Cu(CH3CH2CH(NH2)CH2O)2·H2O] neutral species. The two CuII complexes are not covalently bonded to the CuICN networks. Strong O—H⋯O hydrogen bonds link the CuII complexes into pairs and the pairs are hydrogen bonded into chains along the crystallographic b axis via the hydrate water molecule. In addition, O—H⋯(CN) and N—H⋯(CN) hydrogen bonds link the cations to the CuCN network. In the honeycomb polymeric moiety, all bridging cyanido ligands are disordered over two orientations, head-to-tail and tail-to-head, with occupancies for C and N atoms varying for each CN group.

The molecules of the title compound form acid–acid homodimers in the crystal structure.
In the title compound, C14H14O3, the dihedral angle between the aromatic rings is 39.76 (9)°. In the crystal, the molecules associate to form centrosymmetric acid–acid dimers linked by pairwise O—H⋯O hydrogen bonds. The precision of the geometric parameters in the present single-crystal study is about an order of magnitude better than the previous powder diffraction study [Chattopadhyay et al. (2013#).

In the title compound, the 2-carboxyquinolinium cation, the [SnCl6]2– anion (site symmetry
) and the water molecule of crystallization are held together by hydrogen bonds, π–π stacking and C—Cl⋯π interactions.
In the hydrated title salt, (C10H8NO2)2[SnCl6]·2H2O, the tin(IV) atom is located about a center of inversion. In the crystal structure, the organic cation, the octahedral inorganic anion and the water molecule of crystallization interact through O—H⋯O, N—H⋯O and O—H⋯Cl hydrogen bonds, supplemented by weak π–π stacking between neighboring cations, and C—Cl⋯π interactions.
