catena-Poly[[zinc(II)-bis­[μ-1,3-bis­(imidazol-1-ylmeth­yl)benzene-κ(2) N (3):N (3′)]] dinitrate methanol solvate]

In the title coordination compound, {[Zn(C(14)H(14)N(4))(2)](NO(3))(2)·CH(3)OH}(n), the cationic complex forms a looped chain containing 24-membered M (2) L (2) rings. The ligand adopts two distinct conformations that are alternated in subsequent loops. The Zn(II) ion displays a slightly distorted tetra­hedral geometry being coordinated by four N atoms from four 1,3-bis­(imidazol-1-ylmeth­yl)benzene ligands. The nitrate ions and methanol solvent mol­ecules are located between adjacent double-stranded chains and participate in an extensive net of O—H⋯O and C—H⋯O hydrogen bonds. The resulting three-dimensional assembly is further stabilized by π–π inter­actions between benzene rings [centroid–centroid distances = 3.878 (2) and 3.853 (2) Å].
