Source of materials

To a solution of NiCl2 ⋅ 6H2O (0.2670 g, 1.123 mmol) in EtOH (30 mL) was added 2,4,6-tri-2-pyridyl-1,3,5-triazine (tptz; 0.2814 g, 0.901 mmol) and stirred for 12 h at room temperature. The formed precipitate was separated by filtration, washed with EtOH and acetone, and dried at 50 °C, to give a pale green powder (0.3363 g). Crystals were obtained by slow evaporation from a pyridine (py) solution at 60 °C.

Experimental details

Hydrogen atoms were positioned geometrically and allowed to ride on their parent atoms with d(C—H) = 0.94 Å and Uiso(H) = 1.2Ueq(C) with the help of the SHELXL program (AFIX 43 option) [2]. The highest peak (0.36 e Å−3) and the deepest hole (−0.24 e Å−3) in the difference Fourier map are located 1.19 Å and 1.02 Å from the atoms Ni1 and C2, respectively.

Comment

This contribution is part of my continuing interest in the structural chemistry of metal complexes containing tptz ligand [5], [6], [7], [8]. Single crystals of the title compound [NiCl2(py)(tptz)] were unexpectedly obtained during crystallization from a pyridine solution of the reaction product.

In the title complex, the central Ni(II) ion is six-coordinated in a distorted octahedral manner by three N atoms of the tridentate tptz ligand, two Cl atoms and one N atom from the pyridine ligand. The tight N—Ni—N chelating angles (¡N1—Ni1—N4 = 77.23(8)° and ¡N1—Ni1—N6 = 76.73(8)°) significantly contribute the distortion of the octahedron. The apical Cl1—Ni1—Cl2, N1—Ni1—N7, and N4—Ni1—N6 bond angles are 172.62(2)°, 176.66(7)° and 153.93(8)°, respectively. The Ni—N4/N6pyridyl bonds (2.128(2) and 2.152(2) Å) are slightly longer than the Ni—N1triazine bond (1.978(2) Å) and Ni—N7py bond (2.076(2) Å). In the crystal structure, the two pyridyl rings coordinated to the Ni atom are located approximately parallel to the triazine ring, making dihedral angles of 2.0(2)° and 3.7(2)°. The dihedral angle between the uncoordinated pyridyl ring and triazine ring is 11.3(1)°. The nearly planar pyridine (N7–-C23) rings are twisted with the dihedral angle of 65.88(5)° between the ring plane and the least-squares plane of the tptz ligand. The complex displays intramolecular C—H⋯Cl hydrogen bonds with d(C⋯Cl) = 3.227–3.305(3) Å. Pairs of complex molecules are assembled by intermolecular C—H⋯Cl hydrogen bonds with d(C⋯Cl) = 3.347(3) Å. These pairs are stacked in columns along [100]. In the columns, numerous π–π interactions are present. The shortest distance between Cg1 (the centroid of ring N1—C13) and Cg2i (the centroid of ring N6—C18; symmetry code i: −x, −y, 1 − z) is 4.049(1) Å, and the dihedral angle between the ring planes is 3.7(1)° [4].
