The MnII ion in the title complex, [MnCl2(C18H12N6)], 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 intermolecular C—H⋯Cl hydrogen bonds, forming one-dimensional chains. In the column, intermolecular π–π interactions 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].

Supporting information
To a solution of MnCl2.4H2O (0.2969 g, 1.50 mmol) in MeOH (30 ml) was added 2,4,6-tri-2-pyridyl-1,3,5-triazine (0.1561 g, 0.50 mmol) and stirred for 3 h at room temperature. The formed precipitate was separated by filtration and washed with MeOH and dried at 50 °C, to give a yellow powder (0.1355 g). Crystals suitable for X-ray analysis were obtained by slow evaporation from an N,N-dimethylformamide (DMF) solution at 60 °C.
All H atoms were located from Fourier difference maps and refined isotropically: C—H = 0.91 (3)–0.99 (3) Å.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The crystal structure of the title complex, [MnCl2(tptz)] (tptz = 2,4,6-tri-2-pyridyl-1,3,5-triazine, C18H12N6), was previously reported in the triclinic space group P1 (Ha, 2010). The structure presented herein is essentially the same as the published structure and represents a monoclinic polymorph.
The MnII ion in the complex is five-coordinated in an approximately square-pyramidal geometry by three N atoms of the tridentate tptz ligand and two chloride anions (Fig. 1). While the Mn—Cl bond lengths are almost equal, the Mn—N bond lengths are somewhat different (Table 1). The Mn1—N4/6(pyridyl) bonds are slightly longer than the Mn1—N1(triazine) bond. 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)°. The complexes are stacked in columns along the c axis and linked by intermolecular C—H···Cl hydrogen bonds, forming one-dimensional chains (Fig. 2 and Table 2). There are also intramolecular C—H···N hydrogen bonds (Table 2). In the column, intermolecular π-π interactions between the six-membered rings are present, the shortest centroid-centroid distance being 3.623 (2) Å.
