The crystal structure of a NiII complex with a tridentate chiral ligand has been determined with a final R of 0.042. The crystals were hexagonal, space group P61 with Z = 6, a = b = 18.498 (2), c = 16.328 (2) Å. The complex shows local tetrahedral (skewed) coordination of the metal by two salicyladimine ligands with a tetrahedrality angle of 89.4 (2)° and the Ni shifted by 0.13 Å from the geometric center of the coordination octahedron, both values being the largest ones observed so far in similar NiII six-coordinate complexes. Also a new, simple classification of six-coordinate bis(salicylaldiminato) complexes, based on the relative positions of coordinating atoms, has been proposed.
