This article presents the structure of a tight stacking coordination polymer, {Mn-4(bpy)(2)(H2O)(2)(HBT C)(4)}n, 1, (bpy = 4,40'-dipyridine, H3BTC = 1,3,5-benzenetricarboxylic acid), which is self-assembled from the combination of MnCl2, H3BTC and bpy ligands via hydrothermal synthesis, and which has been further characterized by IR, element analysis, TG-DTA, variable-temperature magnetic susceptibility measurements. The overall structure of polymer 1 is the 3D interdigitating arrangement, constructed from the eight-connected Mn4 tetramer. Further, the magnetic measurements reveal that polymer 1 displays a weak antiferromagnetic behavior with theta = - 3.36K between Mn(II) ions in the electronic configuration of d(5) high spin (S = 5/2).
