The crystal and Molecular structure of [K(18-crown-6)](Bi(SCN)Cl3] has been deterained by X-ray diffraction Method. Its crystal is triclinic, space group Pl,with a = 9.233(4), b = 11.661(5), c=11.738(5)A,a= 81.82(4)° ,β=71.47(4)°,γ=75.55(4)°, and Z = 2. The final structural refine-ment converged with unweighted and weighted R factors of 0.051 and 0.047 for 2924 observed reflections. Results of the structure analysis indicate that the K+ ion enters the cavity of the 18-crown-6 to form the complex cation and one Bi(Ⅲ) atom, one SCN ligand and three Cl atoms fora the anion. Each Bi(Ⅲ) atoa is coordinated by four Cl atoas, of which two are shared with other Bi(Ⅲ) atom, one N atom and one S atoa from two SCN ligands respectively shared with a third Bi(Ⅲ) atoa, forming octahedral geometry.
