Bis[1,1′-(1,3-phenyl­enedimethyl­ene)di(1H-imidazol-3-ium)] β-octa­molybdate

In the title compound, (C₁₄H₁₆N₄)₂[Mo₈O₂₆], the β-octa­molybdate anion is centrosymmetric. N—H...O hydrogen bonds link the diimidazolium cations and the polyoxidoanions into a chain structure along [100]. π–π inter­actions between the imidazole rings and between the imidazole and benzene rings [centroid–centroid distances = 3.611 (2) and 3.689 (3) Å, respectively] connect the chains.

Aqua­cyanido{6,6′-dimeth­oxy-2,2′-[1,2-phenyl­enebis(nitrilo­methanylyl­idene)]diphenolato}cobalt(III) acetonitrile hemisolvate

In the title complex, [Co(C₂₂H₁₈N₂O₄)(CN)(H₂O)]·0.5CH₃CN, the Co^III cation is N,N′,O,O′-chelated by a 6,6′-dimeth­oxy-2,2′-[1,2-phenyl­enebis(nitrilo­methanylyl­idene)]diphenolate dianion, and is further coordinated by a cyanide anion and a water mol­ecule in the axial sites, completing a distorted octa­hedral coordination geometry. In the crystal, pairs of bifurcated O—H...(O,O) hydrogen bonds link adjacent mol­ecules, forming centrosymmetric dimers. The acetonitrile solvent mol­ecule shows 0.5 occupancy.

3-Benzyl­sulfanyl-1H-1,2,4-triazol-5-amine

In the title mol­ecule, C₉H₁₀N₄S, the dihedral angle between the benzene and triazole rings is 81.05 (5)°. In the crystal, N—H...N hydrogen bonds link the mol­ecules into infinite zigzag chains along [010].

4-(2,2-Difluoro-1,3-benzodioxol-4-yl)-1H-pyrrole-3-carbonitrile

In the title compound, C₁₂H₆F₂N₂O₂, the 2,2-difluoro-1,3-benzodioxole ring system is approximately planar [maximum deviation = 0.012 (2) Å] and its mean plane is twisted with respect to the pyrrole ring, making a dihedral angle of 2.51 (9)°. In the crystal, N—H...N hydrogen bonds link the mol­ecules into chains running along the a axis. π–π stacking is also observed between parallel benzene rings of adjacent mol­ecules, the centroid–centroid distance being 3.7527 (13) Å.

Ethane-1,2-diaminium (R)-2-[4-(1-carboxyl­atoeth­oxy)phen­oxy]acetate

In the title compound, C₂H₁₀N₂²⁺·C₁₁H₁₀O₆²⁻, the two acetate groups of the cation form dihedral angles of 74.2 (4) and 63.9 (5)° with the central benzene ring. In the crystal, N—H...O hydrogen bonds link the cations and anions into layers parallel to the ab plane.
