Iodido[5-methyl-1H-benzimidazole-2(3H)-thione-κS]bis­(triphenyl­phosphane-κP)copper(I) methanol monosolvate

In the title compound, [CuI(C₈H₈N₂S)(C₁₈H₁₅P)₂]·CH₃OH, the coordination environment around the Cu^I atom is distorted tetra­hedral, defined by two P atoms of two triphenyl­phosphane ligands, one S atom of a 5-methyl-1H-benzimidazole-2(3H)-thione ligand and one I atom. The complex mol­ecules and the methanol solvent mol­ecules are connected via N—H...O and O—H...I hydrogen bonds, forming a chain along [010]. An intra­molecular N—H...I hydrogen bond is also observed.

3-Amino-1H-1,2,4-triazole-5(4H)-thione–4,4′-bipyridine (1/1)

The title two-component mol­ecular crystal, C₁₀H₈N₂·C₂H₄N₄S, was obtained unexpectedly by reaction of Zn(NO₃)₂·6H₂O, NH₄BF₄ with 3-amino-1,2,4-triazole-5-thione (3-AMT) and 4,4′-bipyridine in water. The dihedral angle between the pyridine rings in the 4,4′-bipyridine molecule is 17.00 (13)°. In the crystal, N—H...N and N—H...S hydrogen bonds between the components lead to the formation of a three-dimensional network. Furthermore, the structure features face-to-face π–π stacking inter­actions between the 4,4′-bipyridine and triazole rings, with a centroid–centroid distance of 2.976 (2) Å.

4,4′-Bipyridine-1,1′-diium bis­(1,3-benzo­thia­zole-2-thiol­ate)

In the title salt, C₁₀H₁₀N₂²⁺·2C₇H₄NS₂⁻, the complete 4,4′-bipyridine-1,1′-diium dication is generated by a center of symmetry. In the crystal, N—H...N hydrogen bonds are observed between the cations and anions.
