Popis: | In the title compound, [Zn(C11H7N6)2(H2O)2], the ZnIIcation, located on an inversion center, isN,N′-chelated by two 5-(pyrazin-2-yl)-3-(pyridin-3-yl)-1,2,4-triazolide anions and is further coordinated by two water molecules in a distorted N4O2octahedral geometry. In the anionic ligand, the pyrazine and pyridine rings are twisted with respect to the central triazole ring by 5.77 (10) and 11.54 (10)°, respectively. In the crystal, classical O—H...N and weak C—H...O hydrogen bonds and π–π stacking interactions between aromatic rings [the centroid–centroid distances between triazole and pyrazine rings, and between triazole and pyridine rings are 3.623 (2) and 3.852 (2) Å, respectively] connect the molecules into a three-dimensional supramolecular architecture. |
