title: catena-Poly[[[bis-(1H-imidazole-κN (3))zinc(II)]-μ2-imidazol-1-ido-κ(2) N:N'] nitrate].
abstract: 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 tetra-hedral 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 inter-action, forming a three-dimensional structure.
