Bis[2,6-bis­(1-methyl-1H-benzimidazol-2-yl-κN³)pyridine-κN]zinc dipicrate methanol disolvate

In the title compound, [Zn(C₂₁H₁₇N₅)₂](C₆H₂N₃O₇)₂·2CH₃OH, the Zn^II atom is coordinated by six N atoms from two tridentate 2,6-bis­(1-methyl-1H-benzimidazol-2-yl)pyridine ligands in a distorted octa­hedral environment. In the crystal, the picrate anions and methanol solvent mol­ecules are connected by O—H...O hydrogen bonds. Weak inter­molecular C—H...O hydrogen bonds are also observed.

2,3-Bis(thio­phen-2-yl)pyrazine­[2,3-f][1,10]phenanthroline

The mol­ecule of the title compound, C₂₂H₁₂N₄S₂, shows no crystallographic symmetry. The thiophene rings form different dihedral angles [40.15 (9) and 15.43 (10)°] with the pyrazine ring. A strong π–π stacking inter­action occurs between adjacent pyrazine­[2,3-f][1,10]phenanthroline units with an inter­planar distance of 3.4352 (16) Å.
