catena-Polybis­(1H-imidazole-κN3)zinc(II)-μ2-imidazol-1-ido-κ2N:N′ nitrate

摘要

The title compound, {[Zn(C3H3N2)(C3H4N2)2]NO3}n, is a one-dimensional coordination polymer along [01-1] with the Zn^II atom coordinating to four imidazole/imidazolide rings. The Zn^II atom has a regular tetra­hedral geometry with the planes of the two monodentate imidazole rings inclined to one another by 87.94 (17)°, while the planes of the bridging imidazolide rings are inclined to one another by 39.06 (17)°. In the crystal, the chains are linked via bifurcated N—H⋯(O,O) hydrogen bonds, forming sheets parallel to (001). These two-dimensional networks are linked via C—H⋯O hydrogen bonds and a C—H⋯π inter­action, forming a three-dimensional structure.
