catena-Poly[[bis­(1-methyl-1H-imidazole-κN (3))zinc]-μ-3-nitro­phthalato-κ(2) O (1):O(2)]

In the title complex, [Zn(C(8)H(3)NO(6))(C(4)H(6)N(2))(2)](n), the carboxyl­ate groups of the 3-nitro­phthalate dianion ligand coordinate the Zn(II) ion in a bis-monodentate mode. The Zn(II) ion shows distorted tetra­hedral coordination as it is bonded to two O atoms from the carboxyl­ate groups of symmetry-related 3-nitro­phthalate anions and two N atoms of two independent 1-methyl­imidazole mol­ecules. The bridging 3-nitro­phthalate ligand allows the formation of one-dimensional chains in the c direction. The crystal structure is further stabilized by weak inter­molecular C—H⋯O hydrogen bonds.
