In the title compound, [Ni2Cl4(C18H12N6)2], the NiII ions are hexa-coordinated in a distorted octahedral coordination environment defined by three N atoms of the tridentate 2,4,6-tri-2-pyridyl-1,3,5-triazine ligand and three Cl− anions in a meridional geometry. The two NiII ions are bridged by two Cl anionic ligands, thereby forming a dinuclear complex. A crystallographic centre of inversion is located at the centroid of the Ni2Cl2 ring.

Structure description
With reference to the title compound, [Ni2Cl4(tptz)2] (tptz = 2,4,6-tri-2-pyridyl-1,3,5-triazine), the crystal structures of related chlorido NiII complexes [NiCl2(tptz)(CH3OH)] (Hadadzadeh et al., 2012), [NiCl(H-tptz)(H2O)2]Cl2·2H2O (Zibaseresht & Hartshorn, 2005) and [NiCl2(py)(tptz)] (py = pyridine) (Ha, 2019) have been determined previously.
In the complex, the two NiII cations are bridged by two chlorido ligands to form a dinuclear complex. A crystallographic centre of inversion is located at the centroid of the Ni2Cl2 ring. The therefore contains one half of the complex (Fig. 1). Each NiII atom is hexa-coordinated in a considerably distorted octahedral coordination environment defined by three N atoms of the tridentate tptz ligand, two bridging Cl− ligands and one terminal Cl− anion. The main contributions to the distortion are the tight N—Ni—N chelating angles [N1—Ni1—N4 = 76.96 (6)° and N1—Ni1—N6 = 77.52 (6)°] and the chlorido bridges, which result in a non-linear trans arrangement of the N4—Ni1—N6 and N1—Ni1—Cl axes [N4—Ni1—N6 = 154.46 (6)° and N1—Ni1—Cl1 = 169.87 (5)°]. On the other hand the Cl2—Ni1—Cl1i axis (symmetry code: (i) −x, −y + 1, −z) is almost linear [Cl2—Ni1—Cl1i = 176.25 (2)°]. The Ni—N(pyridyl) bonds [Ni1—N4/N6 = 2.130 (2) and 2.129 (2) Å] are slightly longer than the Ni—N(triazine) bond [Ni1—N1 = 1.970 (2) Å]. The three Ni—Cl bond lengths are somewhat different [Ni1—Cl1i = 2.5812 (5), Ni1—Cl1 = 2.3326 (5) and Ni1—Cl2 = 2.3538 (5) Å]. The two pyridyl rings that coordinat to the NiII atom are located approximately parallel to the respective triazine ring, making dihedral angles of 4.51 (6) and 4.95 (6)°, respectively. The dihedral angle between the non-coordinating pyridyl substituent and the triazine ring is 7.56 (6)°.
The complex displays numerous intermolecular π–π interactions between adjacent six-membered rings. For Cg1 (the centroid of ring N5/C8–C12) and Cg2ii [the centroid of ring N6/C14–C18; symmetry code: (ii) x, −y + , z − ], the centroid–centroid distance is 4.138 (1) Å and the dihedral angle between the ring planes is 5.44 (10)°. In addition, the complex reveals intermolecular C—H⋯Cl hydrogen bonds with distances of 2.773 (3)–3.605 (2) Å between the donor and acceptor atoms, to stabilize the (Table 1, Fig. 2).
Synthesis and crystallization
To a solution of NiCl2·6 H2O (0.2670 g, 1.123 mmol) in ethanol (30 ml) was added 2,4,6-tri-2-pyridyl-1,3,5-triazine (0.2814 g, 0.901 mmol). The solution was stirred for 12 h at room temperature. The formed precipitate was separated by filtration, washed with ethanol and acetone, and dried at 323 K, to give a pale-green powder (0.3363 g, 84%). Brown crystals suitable for X-ray analysis were obtained by slow evaporation from a dimethyl sulfoxide (DMSO) solution at 363 K.
Refinement
Crystal data, data collection and structure . The remaining maximum (0.33 e Å−3) and minimum (−0.20 e Å−3) electron density in the difference Fourier map are located 0.73 and 1.28 Å, respectively, from atoms C2 and C9.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
Refinement. Hydrogen atoms on C atoms were positioned geometrically and allowed to ride on their respective parent atoms: C—H = 0.94 Å and Uiso(H) = 1.2 Ueq(C). |
