This research focuses on the synthesis and structural characterization of three new RuII polypyridyl complexes containing α-diimine ligands with one PF6− counter-ion. The investigation employs a combination of spectroscopic and X-ray diffraction methods to characterize the complexes.

The structure of a CO2 reduction photocatalyst prototype, the first cis-dicarbonyl ruthenium(II) tetrapyrrole complex, has been determined by X-ray and electron diffraction to have an unprecedented seesaw-coordinated biladiene ligand.

The structure of the title compound exhibits disorder around a
axis. The 4-methoxypyridine ligands have a propeller-like arrangement around the ruthenium at 52.01° from the RuN4 plane.

The crystal structures of five compounds in the Al–Ru–Si system with approximate compositions ∼Ru16(Al0.78Si0.22)47 (I), ∼Ru9(Al0.70Si0.30)32 (II), ∼Ru10(Al0.67Si0.33)41 (III), ∼Ru(Al0.57Si0.43)5 (IV) and ∼Ru2(Al0.46Si0.54)9 (V) are presented. Notably, the crystal structure of (I) can be related to that of a cubic rational crystalline approximant to an icosahedral quasicrystal through crystallographic shear and then unit-cell twinning.

The title compound, [Ru(C12H14NO2)Cl(η6-C6H6)], exhibits a half-sandwich tripod stand structure and crystallizes in the orthorhombic space group P212121. The arene group is η6 π-coordinated to the Ru atom with a centroid-to-metal distance of 1.6590 (5) Å, with the (S)-2-(4-isopropyl-4,5-dihydrooxazol-2-yl)phenolate chelate ligand forming a bite angle of 86.88 (19)° through its N and phenolate O atoms.

The propensity for the central amine N atom in tris(pyridin-2-yl)amine [or (2-py)3N] to remain sp2-hydridized allows the isolation of complexes containing either κ2- or κ3-(2-py)3N, or both, as in [RuCl{κ2-(2-py)3N}{κ3-(2-py)3N}][SbF6].

cis-[RuCl2{2-(4-methoxyphenyl)-1,8-naphthyridine-κN8}2(CO)2] and the 2-methoxyphenyl derivative exhibit moderate catalytic activity with 100% selectivity for the hydrogen-transfer reaction to acetophenone in the presence of a base.

Two concomitant polymorphs of a ruthenium complex were crystallized. The colour of both crystals was orange but the shapes, as well as the crystal structures, were different. The Hirshfeld surface and fingerprint plot analysis of both isomers satisfactorily explained the difference in melting points.

In the crystal structure of the title compound, the ruthenium(II) metal center is surrounded by two bidentate 2,2′-bipyridine, an isonicotinamide ligand, and a water in a distorted octahedral geometry. Hydrogen bonding is present between counter-ion and ligand.
