{2-[1-(2-Meth­oxy-6-oxidophenyl-κO⁶)ethyl­idene]-N-methyl­hydrazinecarbo­thio­amidato-κ²N²,S}(tri­phenyl­phosphane-κP)palladium(II) ethanol monosolvate

In the title compound, [Pd(C₁₁H₁₃N₃O₂S)(C₁₈H₁₅P)]·C₂H₅OH, the Pd^II atom is tetra­coordinated in a slightly distorted square-planar environment by three donor atoms (NOS) from a thio­semicarbazonate ligand, forming five- and six-membered chelate rings, and a P atom from a neutral tri­phenyl­phosphane group. The five-membered ring adopts a distorted envelope conformation with Pd^II as the flap atom, while the six-membered ring forms a slightly twisted screw-boat conformation. A slightly distorted screw-boat form of a meth­oxy­phenyl group is fused to the six-membered ring. Weak C—H...O inter­actions form dimers in the asymmetric unit and along [001] which help to stabilize the crystal packing.

Desvenlafaxinium chloranilate ethyl acetate solvate

In the cation of the title compound, C₁₆H₂₆NO₂⁺·C₆HCl₂O₄⁻·C₄H₈O₂, the 1-hy­droxy-cyclo­hexyl ring adopts a slightly distorted chair conformation. The dihedral angle between the mean planes of the 1-hy­droxy­cyclo­hexyl and 4-hy­droxy­phenyl rings is 84.0 (8)°. In the anion, the hydroxyl H atom is twisted slightly out of the ring plane with a C—C—O—H torsion angle of −171.9°. Disorder was modeled for the methyl group of the acetate group in the solvate with an occupancy ratio of 0.583 (15): 0.417 (15). In the crystal, O—H...O hydrogen bonds are observed between cations and between cations and anions, while bifuricated N—H...(O,O) cation–anion hydrogen bonds are also present, forming chains along [010] and [100]. In addition weak cation–anion and cation–solvate C—H...O inter­actions occur.

3-(1H-Imidazol-1-yl)propanaminium picrate

In the title salt [systematic name: 3-(1H-imidazol-1-yl)propanaminium 2,4,6-tri­nitro­phenolate], C₆H₁₂N₃⁺·C₆H₂N₃O₇⁻, there are five independent cation–anion pairs (A, B, C, D, E) in the asymmetric unit. In the cation, the ammonium group is protonated with the amino­propyl group nearly at right angles to the mean plane of the imidazole ring showing C—N—C—C torsion angles ranging from 79.6 (2) to 99.79 (19)° in the five cations. The nitro groups in the anion are twisted from the benzene mean plane with maximum dihedral angles subtended by nitro substituents ortho to the phenolate O atom of 26.0 (2) and 37.3 (7) (A), 28.9 (5) and 35.3 (1) (B), 34.7 (7) and 36.9 (7) (C), 14.7 (4) and 36.9 (2) (D) and 33.1 (1) and 35.4 (3)° (E). In contrast, the nitro groups in the para positions lie much closer to the aromatic ring plane, subtending dihedral angles of 1.8 (3) (A), 3.5 (3) (B), 6.03 (C), 2.1 (3) (D) and 7.7 (1)° (E). Disorder is observed for one O atom of an ortho nitro group in anion D with an occupancy ratio of 0.53 (5):0.47 (5). In the crystal, N—H...O cation–anion and N—H...N cation–cation hydrogen bonds are observed, linking the ions into chains along [010]. In addition, weak C—H...O cation–anion inter­actions occur.
