Di­chlorido­(pyridine-κN)[2,3,5,6-tetra­kis­(pyridin-2-yl)pyrazine-κ3N2,N1,N6]nickel(II)

ABSTRACT: The central NiII ion has an N4Cl2 octa­hedral coordination sphere defined by three N atoms of the tridentate 2,3,5,6-tetra-2-pyridyl­pyrazine ligand, one N atom of the pyridine ligand and two Cl− anions. In the title complex, [NiCl2(C5H5N)(C24H16N6)], the NiII ion is six-coordinated in a distorted octa­hedral coordination environment defined by three N atoms of the tridentate 2,3,5,6-tetra-2-pyridyl­pyrazine 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].
