The Cs8[W2(CN)16]×3H2O compound
crystallizes in the monoclinic system (space group P21/ñ 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.
