Aqua­(benzamidato-κN)bis­[3,5-difluoro-2-(pyridin-2-yl)phenyl-κC¹]iridium(III) methanol monosolvate

In the title compound, [Ir(C₁₁H₆F₂N)₂(C₇H₆NO)(H₂O)]·CH₃OH, the Ir^III ion adopts an octa­hedral geometry, and is coordinated by two 3,5-difluoro-2-(pyridin-2-yl)phenyl ligands, one mol­ecule of water and one benzamidate anion. The two 2-(4,6-difluoro­phen­yl)pyridyl ligands are arranged in a cis-C,C′ and trans-N,N′ fashion. Additionally, there is a bystanding methanol mol­ecule outside the coordination sphere of the Ir^III ion. In the crystal, mol­ecules of the title compound are linked by O—H...O and O—H...N hydrogen bonds. One F atom of each ligand is equally disordered over two sites. The C atom of the solvent molecule is likewise disordered over two sites in a 0.589 (11):0.411 (11) ratio.

Bis[5-(pyridin-2-yl)pyrazine-2-carbo­nitrile-κ²N⁴,N⁵](trifluoro­acetato-κO)silver(I)

In the asymmetric unit of the title compound, [Ag(C₁₀H₆N₄)₂(CF₃CO₂)], there two mononuclear but slightly different complex units. In each, two κ²N:N-chelating 5-(pyridin-2-yl)pyrazine-2-carbonitrile ligands surround the Ag^I atom, giving an N₄O square-pyramidal coordination geometry with one trifluoro­acetate O atom at the apex. The difference between the two lies in the Ag—N bond lengths: in one complex, three normal [range 2.272 (5)–2.552 (5) Å] and one long [2.706 (4) Å] and in the second, two normal [2.254 (5) and 2.290 (5) Å] and two long [2.647 (5) and 2.675 (5) Å] are present. Short inter­molecular F...F contacts [2.586 (4) Å] and weak π–π stacking inter­actions [minimum ring centroid separation 3.836 (5) Å] between pyridyl and pyrazinyl rings connect the complex units, forming columns which extend along the b-axis direction.
