A one-dimensional chain-like coordination polymer [Mn(phen)(2,4,6-TMBA)2(H2O)]n has been synthesized from 2,4,6-trimethylbenzoic acid, 1,10-phenanthroline and anhydrous manga- nese(Ⅱ ) sulfate and then characterized. Crystal data for this complex: tetragonal, space group I41, a = 2.05643(16), b = 2.05643(16), c = 1.3939(2) nm, V = 5.8946(11) nm3, Mr = 579.54, Z = 8, Dc = 1.306 g/cm3, μ(MoKα) = 0.490 mm-1, F(000) = 2424, S = 0.985, the final R = 0.0411 and wR = 0.0950. The Flack factor is -0.01(2). The crystal structure shows that two neighboring man- ganese(Ⅱ ) ions are linked together by one bridge-chelating 2,4,6-trimethylbenzoic group, forming a one-dimensional chain structure. The manganese(Ⅱ ) ion is coordinated with two nitrogen atoms of one 1,10-phenanthroline, three oxygen atoms from three 2,4,6-trimethylbenzoic acids and one water oxygen atom, giving a distorted octahedral coordination geometry. The cyclic voltametric behavior of the complex was also investigated.
