The title compound, [Ni(C21H15N2S2)(2)], has a novel cis configuration with
two fluorene moieties on the same side. The Ni atom is in a square-planar
configuration. The molecular packing is stabilized by intramolecular stacki
ng between the fluorene moieties and extensive C-H . . . pi interactions.
