In the title nickel-tungsten sulfido mixed-metal complex {tetraethylammonium (1-pyrrolidinecarbodithioato-2κ2S,S′)-di-μ-thio-1:2κ4S-dithio-1κ2S– nickeltungsten(NiW); [N(C2H5)4][NiWS4(S2CNC4H8)]}, the Ni atom is fourfold coordinated by a pyrrolidine-derived dithiocarbamate and a tetrathiotungstate moiety. Dithiocarbamate and tetrathiotungstate act as bidentate ligands, each chelating via two S atoms to the Ni atom, thus forming an approximately square planar geometry. The Ni—W distance is 2.761 (1) Å. The Ni—Sbridge—W angles are 77.13 (8) and 77.08 (9)°. The four Ni—S distances are identical within s.u.'s and average 2.205 (3) Å. The WS4 moiety is a distorted tetrahedron with S—W—S angles ranging from 102.3 (1) to 111.8 (1)°. The two terminal W—S distances are 2.149 (3) and 2.151 (3) Å, while the bridging W—S distances are 2.221 (2) and 2.226 (3) Å.
