The asymmetric unit of the title compound, [MnBr(2)(C(8)H(6)N(4))(2)]·CH(3)NO(2), contains one half of a neutral Mn(II) complex and one half of a nitro-methane solvent mol-ecule, the complete mol-ecules being generated by the application of twofold symmetry. In the complex, the Mn(II) ion has a distorted cis-Br(2)N(4) octa-hedral coordination geometry defined by four N atoms of the two chelating 2,2'-bipyrimidine ligands and two Br(-) ions. There are intra- and inter-molecular C-H⋯Br and C-H⋯N contacts.
标题化合物[MnBr₂(C₈H₆N₄)₂]·CH₃NO₂的不对称单元包含一个中性Mn(II)配合物的一半和一个硝基甲烷溶剂分子的一半，完整的分子通过二重对称性生成。在配合物中，Mn(II)离子具有由两个螯合的2,2'-联嘧啶配体的四个N原子和两个Br⁻离子定义的扭曲的顺式Br₂N₄八面体配位几何结构。存在分子内和分子间的C-H⋯Br和C-H⋯N接触。
