Abstract: In the polymeric title compound, {[Mn₂(SO₄)₂(C₃₀H₃₆N₆)(H₂O)₂]·6H₂O}_n, the two Mn²⁺ ions are bridged by two sulfate anions to form dinuclear complexes, and these dinuclear species are linked by the hexadentate ligand N,N,N',N'-tetrakis(2-pyridylmethyl)hexane-1,6-diamine (tphn), forming a one-dimensional chain structure running in the [101] direction. The repeat unit of the polymer, Mn₂(SO₄)₂(H₂O)₂(tphn), is disposed about a twofold axis passing through the centre of the dinuclear unit. The coordination geometry around the Mn centre is distorted octahedral. Two methylene groups are each disordered equally over two positions.
