Ilmenite-type Na₂(Fe_2/3Te_4/3)O₆

Na₂(Fe_2/3Te_4/3)O₆ was obtained under hydro­thermal conditions and adopts the ilmenite (FeTiO₃) structure type.

trans-Di­chlorido­bis­(secnidazole-κN³)copper(II)

The crystal structure of the title complex is stabilized by inter­molecular O—H⋯Cl hydrogen bonds, forming (18) ring motifs.

(5-Fluoro-2,6-dioxo-1,2,3,6-tetra­hydro­pyrimidin-1-ido-κN¹)(1,4,8,11-tetra­aza­cyclo­tetra­decane-κ⁴N)zinc(II) perchlorate

In the structure of the title complex, the zinc(II) ion forms coordination bonds with the four nitro­gen atoms of cyclam as well as with the nitro­gen atom of a deprotonated 5-fluoro­uracil ion. Cyclam adopts a trans-I type conformation within this structure. The coordination structure of the zinc(II) ion is a square pyramid with a distorted base plane formed by the four nitro­gen atoms of the cyclam.

Chlorido­(2-{(2-hy­droxy­eth­yl)[tris­(hy­droxy­meth­yl)meth­yl]amino}­ethano­lato-κ⁵N,O,O′,O′′,O′′′)copper(II)

The crystal structure of the title complex features O—H⋯O hydrogen bonds, which form (8), (16), (20) and (22) ring motifs.

Tetra­kis(2,4,6-tri­methyl­anilido)tin(IV)

The mol­ecular structure of Sn(NHMes)₄ is defined by a central tin(IV) atom that is coordinated by four NHMes groups in a distorted tetra­hedral arrangement.

Octa­kis(di­butyl­ammonium) deca­molybdate(VI)

(C₈H₂₀N)₈[Mo₁₀O₃₄] comprises a centrosymmetric deca­molybdate polyanion linked through N—H⋯O hydrogen bonds to di­butyl­ammonium counter-cations.

Methyl 2-hy­droxy-4-iodo­benzoate

The title compound forms a sheet structure of dimers exhibiting intra- and inter­molecular hydrogen bonds.

(S)-2-Carb­oxy­ethyl L-cysteinyl sulfone

The mol­ecule is a zwitterion, with a protonated α-amino group and a deprotonated α-carboxyl group. Within the crystal, the mol­ecules are linked by a system of hydrogen bonds formed by both the protonated and deprotonated carb­oxy­lic groups, and the protonated ammonium group.

2-(10-Bromo­anthracen-9-yl)-N-phenyl­aniline

The N—H group of the title compound does not form a hydrogen bond due to steric hindrance.

2-Oxo-2H-chromen-4-yl 3,3-di­methyl­butano­ate

In the crystal of the title compound, the mol­ecules are connected through C—H⋯O hydrogen bonds, generating [100] chains, which are crosslinked by weak π–π stacking inter­actions.
