The title compound, (C16H36N)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 WCu4 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 μ3-S atoms and a terminal Cl atom. The two independent cations lie on positions of symmetry 4̄. © 2004 International Union of Crystallography Printed in Great Britain - all rights reserved.
