Poly[(μ₆-benzene-1,3,5-tri­carboxyl­ato-κ⁶O¹:O^1′:O³:O^3′:O⁵:O^5′)tris­(N,N-di­methyl­formamide-κO)tris­(μ₃-formato-κ³O:O:O′)trizinc(II)]

The asymmetric unit of the title compound, [Zn₃(HCO₂)₃(C₉H₃O₆)(C₃H₇NO)₃]_n, contains one Zn ion, one formate ligand, one N,N-di­methyl­formamide (DMF) ligand and one-third of a benzene-1,3,5-tri­carboxyl­ate (btc) ligand situated on a crystallographic 3 axis. Each Zn^II atom is coordinated by one O atom from a DMF ligand, two O atoms from two btc ligands and three O atoms from three formate ligands in a distorted octa­hedral geometry. The Zn^II atoms are connected by the formate and btc ligands, forming hexanuclear cores, which are linked by btc ligands, constructing a two-dimensional layered network along the ab plane.
