Abstract

In the crystal structure of the title compound, [Ni(C21H19N5O4S2)(C5H5N)2], the metal center is seven-coordinate, with an approximate penta­gonal-bipyramidal configuration. The Ni atom is chelated by a dianionic penta­dentate Schiff base via the pyridine N atom, the two azomethine N atoms and the two sulfonyl O atoms. The latter coordinate to Ni at different distances, viz. 2.3337 (12) and 2.7988 (12) Å. Two apically coordinated pyridine mol­ecules complete the seven-coordin­ate geometry. The dihedral angle between the two pyridine ring planes is 68.25 (6)°.
