Abstract
In the title complex, [NiCl2(C5H5N)(C24H16N6)], the NiII ion is six-coordinated in a distorted octa-hedral coordination environment defined by three N atoms of the tridentate 2,3,5,6-tetra-2-pyridyl-pyrazine ligand, one N atom of the pyridine ligand and two Cl- anions, with the latter being mutually trans. The complex is disposed about a twofold rotation axis along the a axis. The complex molecules are connected in the crystal via C-H⋯Cl, C-H⋯N and π-π [closest inter-centroid separation = 3.7446 (14) Å between pyridyl rings].
