Syntheses, crystal structures and Hirshfeld surface analysis of 4-(4-nitro­phen­yl)piperazin-1-ium tri­fluoro­acetate and 4-(4-nitro­phen­yl)piperazin-1-ium tri­chloro­acetate

The supra­molecular assemblies of the two title structures are one-dimensional: the chain-of-rings motifs are supported by aromatic π–π inter­actions.

Crystal structure of 2-(morpholino)ethyl­ammonium picrate monohydrate

The title compound was synthesized via slow evaporation of an aqueous solution of picric acid with the substituted morpholine base and crystallized with one cation (C₆H₁₅N₂O)⁺, one anion (C₆H₂N₃O₇)⁻ and a water mol­ecule in the asymmetric unit. The morpholine ring in the cation adopts a chair conformation. The structure is stabilized by C–H⋯O, O—H⋯O, O—H⋯N and N—H⋯O hydrogen-bonding inter­actions and π–π stacking. The inter­molecular inter­actions of the synthesized compound were qu­anti­fied by Hirshfeld surface analysis.

Iclaprim and mesylate mol­ecules are linked into a hydrogen-bonded mol­ecular tape, the central section of which is composed of fused rings.

Crystal structures of (Z)-(ethene-1,2-di­yl)bis­(di­phenyl­phosphine sulfide) and its complex with Pt^II dichloride

The crystal structures of the di­sulfide derivative of (Z)-ethene-1,2-bis­(di­phenyl­phosphine) as well as its complex with Pt^II are described here. The structure of the phosphine sulfide features intra­molecular π–π inter­actions and C—H⋯S hydrogen bonds, as well as inter­molecular π–π and C—H⋯π inter­actions. The structure of the platinum(II) complex features inter­molecular C—H⋯Cl and C—H⋯S hydrogen bonds.

Crystal structure of sodium thio­sulfate dihydrate and comparison to the penta­hydrate

Na₂S₂O₃·2H₂O has been known for more than a hundred years but no structural data were known to date. Now, crystals of this compound have been grown at the surface of an aqueous solution of Na₂S₂O₃. The sodium cations are five- to seven-coordinate by thio­sulfate anions and water mol­ecules with the anions acting as mono- and bidentate ligands. The thio­sulfate anions and water mol­ecules are connected by O—H⋯O and O—H⋯S hydrogen bonds of medium strength to form corrugated layers, which are linked by sodium cations.

Crystal structure of bis­(mesit­yl)(pyrrol-1-yl)borane

In the crystal structure of the title compound, the dimesitylboron group acts to reduce the delocalization of the nitro­gen atom's lone pair into the pyrrole ring, with increases in the two N—C bond lengths compared to pyrrole itself. The N—B bond is 1.44125 (15) Å long.
