Accurate intensity integration in the twinned γ-form of o-nitro­aniline

o-Nitro­aniline, C₆H₆N₂O₃, is known to be polymorphic. Difficulties with the unit-cell determination of the γ-form were reported as a consequence of twinning. In this paper, newly recorded diffraction data of the γ-form of o-nitro­aniline are described that were processed taking into account the two twin lattices. The availability of raw data and proper reprocessing using twin lattices is by far superior to efforts to de-twin processed structure factors.

Bis(acetyl­acetonato-κ²O,O′)(N,N,N′,N′-tetra­methyl­ethylenedi­amine-κ²N,N′)magnesium(II)

The central magnesium(II) atom exhibits a nearly octa­hedrally arranged N₂O₄ coordination set from two chelating acetyl­acetonate ligands and one tetra­methyl­ethylenedi­amine ligand.

Bis[(4-methyl­phen­yl)di­phenyl­phosphane-κP](nitrato-κ²O,O′)silver(I)

The synthesis and single-crystal structure description of a silver(I) diphenyl-p-tolyl­phosphine nitrate complex is described.

Bis(4′-chloro-2,2′:6′,2′′-terpyridine-κ³N,N′,N′′)zinc(II) bis­(tri­fluoro­methane­sulfonate)

The crystal structure of the title compound consists of a zinc(II) metal center surrounded by two 4-chloro­terpyridine ligands in a distorted octa­hedral geometry with π–π stacking inter­actions contributing to the crystal packing.

Morpholin-4-ium [5-cyano-6-(4-methyl­phen­yl)-4-(morpholin-4-yl)pyrimidin-2-yl](phenyl­sulfon­yl)amide

The title salt contains morphilinium cations, which bridge pairs of anions through N—H⋯N and N—H⋯(O,N) hydrogen bonds.

2,5,8,11-Tetra­methyl-2,5,8,11-tetra­aza­dodecane-2,11-diium bis­[hy­droxy­tris­(penta­fluoro­phen­yl)borate] benzene 2.5-solvate

The asymmetric unit of the title salt, C₁₂H₃₂N₄²⁺·2C₁₈HBF₁₅O⁻·2.5C₆H₆, which crystallizes in the triclinic space group P, comprises two half [C₁₂H₃₂N₄]²⁺ dications, two [C₁₈HBF₁₅O]⁻ anions, and 2.5 mol­ecules of benzene as solvate.

5-(4-Meth­oxy­phen­yl)-1-[4-(4-meth­oxy­phen­yl)thia­zol-2-yl]-3-[4-(prop-2-yn­yloxy)phen­yl]-4,5-di­hydro-1H-pyrazole

The title mol­ecule contains a central four-ring system in which all of the rings are almost coplanar.

Di­ethyl 4,4′-[octane-1,8-diylbis(­oxy)]dibenzoate

The title centrosymmetric mol­ecule is almost planar.
