title: catena-Poly[[[dibromidomanganese(II)]-μ-2,2'-bipyrimidine-κN,N:N,N]dihydrate].
abstract: The asymmetric unit of the title compound, {[MnBr(2)(C(8)H(6)N(4))]·2H(2)O}(n), contains one half of a repeat unit of the neutral linear coordination polymer and a solvent water mol-ecule, with the Mn(II) ion on a crystallographic twofold axis. In the polymer, inversion-related Mn(II) ions are bridged by the bis-chelating 2,2'-bipyrimidine (bpym) ligands, thereby forming a chain structure along the c-axis direction, and are six-coordinated in a distorted cis-N(4)Br(2) octa-hedral environment by four N atoms of twofold-related bpym ligands and twofold-related bromide anions. In the crystal, the complex polymers and solvent water mol-ecules are linked by inter-molecular O-H⋯Br and C-H⋯O hydrogen bonds, forming a two-dimensional layered structure extending parallel to the ac plane.
