The Cs₈[W₂(CN)₁₆]×3H₂O compound crystallizes in the monoclinic system (space group P2₁/с with cell parameters a = 22.7973(6), b = 9.3261(1), c = 18.4881(4) Å, β = 95.400(2)°, Z = 4, R1 = 0.0463). The W atoms occupy two crystallographically independent sites and the coordination polyhedra of the tungsten atoms are distorted trigonal prisms [W(1)(CN)₈] and [W(2)(CN)₈] with two additional atoms. The Cs atoms occupy eight sites and exhibit various coordination polyhedra: distorted tetragonal antiprisms, distorted pentagonal bipyramids, trigonal prisms with one addition atom, trigonal prisms with two additional atoms, and a 9-vertex polyhedron of irregular shape.
