(η⁶-Benzene)­dichlorido­[di­cyclo­hex­yl(4-iso­propylphen­yl)phosphane-κP]ruthenium(II)

The title complex exhibits a half-sandwich structure with a tripodal piano stool-like arrangement consolidated by non-classical intra- and inter­molecular inter­actions.

trans-Di­chlorido­tetra­kis­(pyridine-4-carbo­nitrile-κN)ruthenium(II) toluene hemisolvate

The propeller-like title complex packs with overlapping carbonitrile groups to form a grid with a significant void volume.

Bis(pyridinium) tetra­chlorido­zincate(II), [Hpy]₂[ZnCl₄]

The structure of the title compound is described in terms of the isostructural cobalt compound with particular regard on the different π–π inter­actions between the pyridinium ions.

(E)-N-(4-Bromo­phen­yl)-1-(quinolin-2-yl)methanimine

The title Schiff base was prepared by condensation of 2-quinoline­carboxaldehyde with 4-bromo­aniline, is reported. Inter­molecular C—H⋯π inter­actions between quinolinyl and bromo­phenyl rings form a three-dimensional supra­molecular network in the crystal packing.

6,7-Di­chloro-2-methyl-3-phenyl­quinoxaline

The title compound was synthesized using the acid catalyst NH₄HF₂ in a water/methanol solution. The extended structure features offset stacked quinoxalines along the [100] direction.

1,3,5-Tri­aza-7-phosphaadamantan-1-ium nitrate

The title salt comprises a N-protonated PTA cation with a nitrate counter-ion.

5-Cyclo­propyl-1-[(4-methyl­benzene)­sulfon­yl]indole-2-carbaldehyde

The crystal structure of 5-cyclo­propyl-1-tosyl-1H-indole-2-carbaldehyde shows a nearly planar indole core, with slipped π–π stacking inter­actions contributing to the crystal packing. Hirshfeld surface analysis indicates that H⋯H, O⋯H/H⋯O and C⋯H/H⋯C contacts make the major contributions to the crystal packing.

Methyl 9-(4-methyl­benzene­sulfon­yl)-4-phenyl-9H-pyrido[3,4-b]indole-3-carboxyl­ate

The crystal structure of a β-carboline, C₂₆H₂₀N₂O₄S, synthesized via 2 + 2+2-cyclo­addition to an alkynylynamide, is presented.

4-[(E)-2-(4-{(E)-2-[4-((E)-2-{4-[(E)-2-(4-Cyanophenyl)ethen­yl]phenyl}ethen­yl)-2,5-bis­(octyl­oxy)phenyl]ethen­yl}phenyl)ethen­yl]benzo­nitrile

The complete mol­ecule of the title compound, which was prepared via a Horner olefination, is generated by a crystallographic centre of symmetry. Whereas the terminal cyano­stilbene units are almost planar, the central dioctoxybenzene unit is substanti­ally tilted, which limits conjugation. van der Waals forces between the alkyl chains connect the mol­ecules, arranged in layers lying parallel to the ac plane.

1-Naphthamide

In the title compound, the dihedral angle between the naphthalene fused-ring system and the amide group is 42.18 (9)°. In the crystal, N—H⋯O hydrogen bonds link the mol­ecules into (100) sheets.
