Chlorido­{2-[(4-chloro­phen­yl)imino­meth­yl]pyridine-κ²N,N′}(η⁶-toluene)­ruthenium(II) hexa­fluoridophosphate

The crystal structure of an arene ruthenium(II) complex bearing a bidentate Schiff base ligand is reported.

Bis(azido-κN)bis­(quinolin-8-amine-κ²N,N′)iron(II) monohydrate

In the title compound, [Fe(N₃)₂(C₉H₈N₂)₂]·H₂O or [Fe(N₃)₂(AQ)₂]·H₂O, the Fe^II ion is distorted octa­hedrally coordinated by two azide ions in a cis position with a syn orientation, while the two amino groups of the AQ ligands are in a cis and the two pyridiyl N atoms are in a trans position.

Bis[(2-meth­oxy­phen­yl)di­phenyl­phosphane-κP](nitrito-κ²O,O′)silver(I)

The synthesis and single-crystal structure description of a silver(I) diphenyl-2-meth­oxy­phenyl­phosphine nitrite complex is described.

2-Oxo-2H-chromen-7-yl tert-butyl­acetate

In the title compound, the dihedral angle between the 2H-chromen-2-one ring system and the tert-butyl­acetate moiety is 72.72 (9)°. In the crystal, the mol­ecules are connected through C—H⋯O hydrogen bonds, generating C(6) chains and R₂²(20) loops that are reinforced by weak aromatic π–π stacking inter­actions.

(E)-1-(2-Hy­droxy­phen­yl)-3-(3-meth­oxy­phen­yl)prop-2-en-1-one

The title compound contains two almost coplanar phenyl rings and an intra­molecular O—H⋯O hydrogen bond.

2-Methyl-4-thio­cyanato­aniline

The title compound is a rhodanided derivative of ortho-toluidine. The mol­ecules are connected into a three-dimensional network in the crystal structure by means of classical hydrogen bonds and C–H⋯N contacts.

rac-4H,5H,6H,7H,8H,9H,10H,11H-Cyclo­deca­[d][1,2,3]selena­diazole-8-carb­oxy­lic acid

The chair-shaped mol­ecules in the crystal consist in two pairs of enanti­omers with two conformations (ratio 1:3), differing only in the position of two ring carbon atoms.

2-[3-(1H-Benzimidazol-2-yl)prop­yl]-1H-benzimidazol-3-ium 3,4,5-tri­hydroxy­benzoate trihydrate

A layered crystal structure built up from alternating cationic and (anionic + water of crystallization) supra­molecular planes parallel to (100) is described for the title hydrated salt.
