The title compound, (C~5~H~12~N)~2~[Ni(C~4~N~2~S~2~)~2~], is a new [Ni(mnt)~2~]^2−^ salt (mnt^2−^ is 1,2-dicyanoethene-1,2-dithiolate) with piperidinium [(PIH)^+^] cations. The Ni^II^ ion lies on an inversion centre and the asymmetric unit contains a (PIH)^+^ cation and one half of the [Ni(mnt)~2~]^

In the title salt, (C~25~H~21~FP)~2~[Ni(C~4~N~2~S~2~)~2~], the Ni^II^ ion lies on an inversion centre and the [Ni(mnt)~2~]^2−^ anion (mnt is maleonitriledithiolate) exhibits a square-planar coordination geometry. The (3-fluorobenzyl)triphenylphosphonium cation adopts a conformation in which the four
, was obtained by the direct reaction of NiCl 2 Á6H 2 O, K 2 imnt and (Bz2NH 2 py) + ÁBr À in water. The Ni II ion lies on an inversion centre and the asymmetric unit contains a (Bz2NH 2 py) + cation and one-half of the Ni(imnt) 2 2À anion. The Ni II ion adopts a square-planar coordination geometry.
