catena-Poly[bis­[bis­(1H-benzotriazole)zinc(II)]-μ₄-benzene-1,2,4,5-tetra­carboxyl­ato], a one-dimensional coordination polymer with double chains

In the title compound, [Zn₂(C₁₀H₂O₈)(C₆H₅N₃)₄]_n, the Zn^II atom has a distorted tetra­hedral coordination geometry, defined by two N atoms and two carboxyl O atoms from two benzotriazole ligands and a benzene-1,2,4,5-tetra­carboxyl­ate ligand. The structure exhibits one-dimensional double chains running along the [100] direction, which further extend into a three-dimensional supramolecular network by π–π stacking.
