Abstract
The Mn(II) ion in the title complex, [MnCl(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 ligand and two chloride anions. In the crystal, the pyridyl rings are located approximately parallel to their carrier triazine ring, making dihedral angles of 5.0 (1), 3.8 (1) and 3.2 (1)°. Intramolecular C-H⋯N hydrogen bonds are present. The complexes are stacked in columns along the c axis and linked by inter-molecular C-H⋯Cl hydrogen bonds, forming one-dimensional chains. In the column, inter-molecular π-π inter-actions between the six-membered rings are present, the shortest centroid-centroid distance being 3.623 (2) Å. The structure reported herein represents a monoclinic polymorph of the previously reported triclinic form [Ha (2010 ▶). Acta Cryst. E66, m262].
