title: Poly[[μ-N,N'-bis-(2-hy-droxy-eth-yl)-N,N,N',N'-tetra-methyl-propane-1,3-diaminium-κ(2) O:O']tetra-μ-bromido-dibromidodimanganese(II)].
abstract: The asymmetric unit of the title three-dimensional coordination polymer, [Mn2Br6(C11H28N2O2)] n , consists of one Mn(II) cation, half of a dicationic N,N'-bis-(2-hy-droxy-eth-yl)-N,N,N',N'-tetra-methyl-propane-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 hy-droxy O atom and by five bromide ions, resulting in a distorted octa-hedral MnBr5O 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.
