The title compound, (C 16 H 36 N) 2 [WS 4 (CuCl) 4 ], has been obtained in a second polymorphic form. The anion, in which four of the six S⋯S edges of the central WS 4 tetrahedron are bridged by CuCl neutral molecular units to give a planar pentanuclear WCu 4 framework, is disordered on a crystallographic fourfold rotation axis, requiring equal occupancy of two sets of four positions for the S atoms. Copper has distorted trigonal planar coordination, involving two μ 3 ‐S atoms and a terminal Cl atom. The two independent cations lie on positions of symmetry .
