The crystal structure of TbKW(CN)8ź7H2O has been solved from X-ray single crystal diffraction data. The compound crystal lizes in the triclinic system, space group P-1, lattice parameters a = 7.6713(7), b = 9.2686(8), c = 14.5523(14) A, a = 80.506(11), b = 87.580(11), g = 77.751(10)°, V = 997.27(16) A3, Z = 2, Dx = 2.385 g cm-3, R1 = 0.0240 and wR2 = 0.0525 for 3623 independ ent reflections. The coordination polyhedra of the tungsten atoms are intermediate between [W(CN)8] tetragonal antiprisms and bicapped trigonal prisms (rectangular faces are centered) and of the terbium atoms [TbN4(H2O)4] tetragonal antiprisms. Part of the cyanogroups act as bridging units, connecting [W(CN)8] and [TbN4(H2O)4] structural units into "slab-like" structure. These slabs are connected via potassium ion to form 3-dimensional structure. The formula of the coordination polymer can be written as {[Tb(H2O)4][K(H2O)][W(CN)8]}nź2nH2O.
