title: Dibromido(2,4,6-tri-2-pyridyl-1,3,5-triazine-κN,N,N)manganese(II).
abstract: The Mn(II) ion in the title complex, [MnBr(2)(C(18)H(12)N(6))], is five-coordinated in a distorted square-pyramidal geometry by three N atoms of the tridentate 2,4,6-tri-2-pyridyl-1,3,5-triazine (tptz) ligand and two bromide anions. In the crystal, the pyridyl rings coordinated to the Mn atom are inclined slightly to their carrier triazine ring [dihedral angles = 8.0 (3) and 7.5 (3)°], whereas the uncoordinated pyridyl ring is located approximately parallel to the triazine ring [dihedral angle = 3.7 (3)°]. The complexes are stacked in columns along the a axis and linked by inter-molecular C-H⋯Br hydrogen bonds, forming chains. In the column, inter-molecular π-π inter-actions between the six-membered rings are present, the shortest centroid-centroid distance being 3.750 (4) Å.
