Abstract: In the title complex, (C₂₂H₂₄P)[Ni(C₃S₅)₂] or (BuPh₃P)[Ni(dmit)₂] (where BuPh₃P is the butyltriphenylphosphonium cation and dmit is the 2-thioxo-1,3-dithiole-4,5-dithiolate anion), each Ni atom is tetracoordinated by four dmit S atoms, forming a nearly square-planar arrangement. The average Ni-S bond length is 2.16Å, much smaller than 2.21Å for the Ni²⁺ ion in [Ni(dmit)₂]^2-. The other bond distances are also shorter, close to the corresponding double-bond value. The [Ni(dmit)₂]^- anions and butyltriphenylphosphonium counter-cations form a layered arrangement in the crystal structure.
