The title methyl­ene-bridged bis-N-heterocyclic carbene (NHC) palladium complex exhibits a distorted square-planar geometry around the palladium center, with the six-membered chelate ring adopting a boat conformation.

{α,α′-Bis[(tert-but­yl)(6-meth­oxy­pyridin-2-yl)phosphino]-o-xylene}(η²-N-methyl­maleinimide)palladium(0) toluene hemisolvate

The solvated title compound, [Pd(C₅H₅NO₂)(C₂₈H₃₈N₂O₂P₂)]·0.5C₇H₈, consists of a palladium(0) atom coordinated by a chelating α,α′-bis­[(tert-but­yl)(6-meth­oxy­pyridin-2-yl)phosphino]-o-xylene ligand and an η²-coordinating N-methyl­maleinimide molecule.

(η⁴-Tri­methyl­ene­methane)(1,1,1-tris­{[bis­(4-meth­oxy­phen­yl)phosphan­yl]meth­yl}ethane)ruthenium(II) di­ethyl ether hemisolvate

In the title complex, the Ru^II atom is coordinated by a 1,1,1-tris­{[bis­(4-meth­oxy­phen­yl)phosphan­yl]meth­yl}ethane ligand in κ³-coordination mode and an η⁴-coordinating tri­methyl­ene­methane ligand.

Tris(2,2′-bi­pyridine)­iron(II) tris­(di­cyano­methyl­idene)methane­diide

The asymmetric unit of the title compound, [Fe(C₁₀H₈N₂)₃][C{C(CN)₂}₃], contains an iron–bipyridyl unit and one third of two crystallographic independent tris­(di­cyano­methyl­idene)methane­diide units. In the crystal, hydrogen bonds between cations and anions form complex layers parallel to (001). These are supplemented by hydrogen bonds perpendicular to the former, leading to a three-dimensional network.

Di­aqua­bis­(DL-α-lipoato-κ²O,O′)manganese(II)

The crystal structure of the title di­aqua­bis­(lipoato-κ²O,O′)manganese(II) complex reveals a distorted octa­hedral geometry around the Mn^II centre. The supra­molecular framework is consolidated by O—H⋯O and C—H⋯S hydrogen bonds.

2-Methyl­imidazolium tetra­kis­(2-thenoyltri­fluoroacetonato-κ²O,O′)neodymium(III)

The title neodymium salt includes anions and cations linked by N—H⋯O hydrogen bonds to form zigzag chains extending along [001] in the crystal.

N-(4-Meth­oxy-2-methyl-5-nitro­phen­yl)acetamide

In the title compound, C₁₀H₁₂N₂O₄, the four substituents lie out of the phenyl plane by varying degrees. In the extended structure, the acetamide NH group donates a hydrogen bond to an acetamide carbonyl O atom, thereby forming chains propagating in the [010] direction.

4,4′-{[(2,2′-Bi­pyridine)-5,5′-dicarbon­yl]bis­(aza­nedi­yl)}bis­(1-methyl­pyridin-1-ium) bis­[hexa­fluorido­phosphate(V)] aceto­nitrile disolvate

In the redox-active title compound, a 2,2-bi­pyridine derivative tethered to two N-methyl­pyridinium moieties as electron reservoirs. The asymmetric unit comprises one half of the divalent bpy cation together with a [PF₆]⁻ anion and a CH₃CN mol­ecule. The crystal structure features hydrogen-bonding and π–π inter­actions.

1-[(2-Bromo­phen­yl)di­phenyl­meth­yl]-3-(tri­fluorometh­yl)-1H-pyrazole–1-(tri­phenyl­meth­yl)-3-(tri­fluoro­meth­yl)-1H-pyrazole (0.638:0.362)

In the title disordered co-crystal, C—H⋯Br hydrogen bonds link the mol­ecules into centrosymmetric dimers, enclosing R²₂(16) ring motifs.

2,3,4,6-Tetra-O-acetyl-1-[(di­methylcarbamo­thioyl)sulfanyl]-β-D-galacto­pyran­ose

The bond lengths in the C—S—C moiety are almost equal, with a shorter formally double C—S bond. The packing involves ‘weak’ hydrogen bonds; the three shortest contacts combine to form layers parallel to the ab plane.

Methyl 3-[(tert-but­oxy­carbon­yl)amino]­benzoate

In the extended structure of the title compound, mol­ecular pairs are connected via N—H⋯O and C—H⋯O hydrogen bonds, generating inversion dimers characterized by R²₂(10) graph-set motifs. These dimers further associate through N—H⋯O and C—H⋯O inter­actions, forming supra­molecular layers lying parallel to the (104) crystallographic plane. Aromatic π–π stacking inter­actions and C—H⋯π contacts contribute to the tri-periodic supra­molecular architecture.

3-(4-Fluoro­phen­yl)imidazo[1,2-a]pyridine-2-carbaldehyde

In the title compound, C—H⋯O and C—H⋯F hydrogen bonds link the mol­ecules into a three-dimensional network.

The crystal structure of a tetra­halogenated bi­cyclo­nonane, C₉H₁₂Br₂Cl₂, is reported. The mol­ecule adopts a distorted twist-chair conformation. The cyclo­propane ring is almost parallel to the plane formed by the four methyl­ene carbon atoms.
