Abstract: This paper reports on the synthesis of the title compound by means of using gel method. The compound was characterized by elemental analysis, IR, MS and differential thermal-thermal gravimetric analysis. Using a four cycle diffractometer determined the crystal structure.The crystal belongs to the triclinic system and the space group is P1with cell parameters, α=9. 097(2)Å, b=15.754(3)Å, c= 16.556(2)Å, α=88.08 (1)°, β=81.29(1)°, γ=86.62(2)°, Z=2. The result of crystal structure analysis shows that the 18-crown-6 coordinates with ammonium to form cation and the Bi(Ⅲ) is coordinated by thiocynates and chloride ions to form a polymeric negative ion chain.
