Poly[(μ(3)-benzene-1,3,5-tricarboxyl­ato-κ(3) O (1):O (3):O (5))(μ(2)-2-methyl­imidazolato-κ(2) N:N′)tris­(2-methyl­imidazole-κN)dizinc(II)]

Hydro­thermal reaction involving zinc nitrate hexa­hydrate, tris­odium benzene-1,3,5-tricarboxyl­ate (Na(3)BTC) and 2-methyl­imidazole (2-MeImH) yielded the title compound, [Zn(2)(C(9)H(3)O(6))(C(4)H(5)N(2))(C(4)H(6)N(2))(3)]. In this mixed-ligand metal-organic compound, Zn(2+) ions are coordinated by N atoms from 2-MeImH mol­ecules and (2-MeIm)(−) ions, as well as by O atoms from (BTC)(3−) ions. This results in two different distorted tetra­hedra, viz. ZnN(3)O and ZnN(2)O(2). These tetra­hedra are inter­connected via (BTC)(3−) ions and N:N′-bridging (2-MeIm)(−) ions, thus forming a layered structure in the bc plane. Hydrogen bonds between the O atoms of carboxyl­ate ions and NH groups of 2-MeImH ligands link the layers into a three-dimensional structure.
