Abstract A new heterocyclic carboxylate ligand, 5-(40- pyridyl)-3-methyl- benzoic acid (Hpmba), was synthesized to construct a Mn(II) coordination polymer, namely [Mn(pmba)2]n (1). Complex 1 crystallizes in monoclinic space group C2/c, with a = 17.44(2), β = 17.040(12), c = 8.680(15) A , β = 111.258(13), V = 2404(5) A 3, and Z = 4. Single-crystal X-ray diffraction studies show that complex 1 has a 3D metal-organic supramolecular framework consisting of double helical chains. Magnetic studies for complex 1 show antiferromagnetic coupling between the nearest Mn(II) ions, with g = 2.11 and J = -10.1 cm-1. Springer Science+Business Media, LLC 2011.
