The target compound was obtained through solvothermal reaction route, which exhibits a 3D layered network. This net represents a rare trinodal (4 2 · 8 4) (4 3 · 6 3) 2 (4 6 · 6 3 · 8 6) 2 topology. A new manganese polymer Mn 3(ptc) 2(H 2O) 4 ( 1) (H 3ptc = Pyridine-2,4,6-tricarboxylic acid) has been solvothermally synthesized and characterized by single-crystal diffraction, IR, TGA and elemental analysis. Compound 1 crystallizes in the triclinic space group P 1 ¯ and shows a fairly complicated structure, which should be attributed to the high connectivity of H 3ptc ligand. Meanwhile, we defined a novel trinodal (4 2 · 8 4)(4 3 · 6 3) 2(4 6 · 6 3 · 8 6) 2 topology net, two types of Mn(II) ions in different chemical environment and ptc 3− anion act as four-connected, four-connected and six-connected node, respectively. The magnetic measurement in the temperature range of 2–300 K displays weak antiferromagnetic coupling interaction between the Mn(II) ions.
