The asymmetric unit of the title polymeric compound, [Zn3(C10H8O4)3(C5H5N)2]n or [Zn3(dmbdc)3(py)2]n (dmbdc = 2,5-dimethylbenzenedicarboxylate; py = pyridine) contains two Zn(II) ions, one of which is located on an inversion centre, one and a half 2,5-dimethylbenzenedicarboxylate ligands and one pyridine ligand. Each ZnO6 octahedron is sandwiched between two ZnO4N square-pyramids, forming a trinuclear zinc secondary building unit (SBU); each SBU is further linked by six 2,5-dimethylbenzenedicarboxylate ligands with six adjacent trinuclear zinc SBU's, forming a two-dimensional layer structure with a (3,6) net. One of the three zinc ions is octahedrally coordinated and the other two are square-pyramidally coordinated. The coordination modes for 2,5-dimethylbenzenedicarboxylates are bis(bidentate) or bidentate-tridentate.
