Rubidium 3-carboxy-4-hydroxy­benzene­sulfonate monohydrate

The title compound, poly­[[rubidium-μ-5-sulfonosalicylic acid] monohydrate], Rb⁺·C₇H₅O₆S⁻·H₂O, the 5-sulfosalicylic acid anion (3-carboxy-4-hydroxy­benzene­sulfonate) has lost the proton of —SO₃H group, but retains the usual intermolecular hydrogen bond between the phenolic and carboxyl­ic O atoms. The Rb⁺ cation is surrounded by eight O atoms. The crystal packing is stabilized by intermolecular O—H...O hydrogen bonds.

1-[2,6-Di­chloro-4-(tri­fluoro­methyl)­phenyl]-5-[(4-di­methyl­amino­benzyl­idene)­amino]-1H-pyrazole-3-carbo­nitrile

The title compound, C₂₀H₁₄Cl₂F₃N₅, is a tricyclic amide with an overall U-shape, each of the the three rings being planar. There are π–π interactions between the pyrazole ring and the benzene ring with the di­methyl­amine substituent.

1-[2,6-Di­chloro-4-(tri­fluoro­methyl)­phenyl]-5-[(4-methoxy­phenyl)­methyl­ene­imino]-1H-pyrazole-3-carbo­nitrile

The title compound, C₁₉H₁₁Cl₂F₃N₄O, is a tricyclic imide with an overall U-shape, each of the the three rings being planar. In the crystal structure, the molecular packing is stabilized by π–π interactions occurring between adjacent methoxy­phenyl rings.

Hexa­carbonyl­hexakis(μ-3,4-di­methyl­benzene­thiol­ato)­triiron(II)

The title complex, [Fe₃(C₈H₉S)₆(CO)₆], contains one Fe^II atom and two Fe(CO)₃ subclusters connected through six 3,4-di­methyl­benzene­thiol­ate (μ₂-S) ligands.
