Poly[[μ-N,N′-bis­(2-hy­droxy­eth­yl)-N,N,N′,N′-tetra­methyl­propane-1,3-diaminium-κ(2) O:O′]tetra-μ-bromido-dibromidodimanganese(II)]

The asymmetric unit of the title three-dimensional coordination polymer, [Mn(2)Br(6)(C(11)H(28)N(2)O(2))](n), consists of one Mn(II) cation, half of a dicationic N,N′-bis­(2-hy­droxy­eth­yl)-N,N,N′,N′-tetra­methyl­propane-1,3-diaminium ligand (L) (the other half being generated by a twofold rotation axis), and three bromide ions. The Mn(II) cation is coordinated by a single L ligand via the hy­droxy O atom and by five bromide ions, resulting in a distorted octa­hedral MnBr(5)O coordination geometry. Four of the bromide ions are bridging to two adjacent Mn(II) atoms, thereby forming polymeric chains along the a and b axes. The L units act as links between neighbouring Mn—(μ-Br)(2)—Mn chains, also forming a polymeric continuum along the c axis, which completes the formation of a three-dimensional network. Classical O—H⋯Br hydrogen bonds are present. The distance between adjacent Mn(II) atoms is 4.022 (1) Å.
