Abstract: A novel super-molecular complex, [Na(DB18C6)(CH₃CN)]₂Mo₆O₁₉, was obtained by solvothermal reaction and characterized by elementary analysis, IR, ¹H NMR, gumbc spectrum and X-Ray diffraction experiment. The compound crystallizes in monoclinic space group P2₁/n with a=1.187 1(3) nm, b=2.096 3(6) nm, c=1.415 8(4) nm, β=110.854(5)° and Z=4. The complex contains four basic units: Na⁺, CH₃CN, DB₁₈C₆和Mo₆O₁₉^2-. Sodium ions located in the cavity of dibenzo-18-crown-6 with 6 Na-O bonds and the crown ether-sodium ion complex is supported on the terminal oxygen atoms of the typical Lindqvist isopolyanion Mo₆O₁₉^2- via the coordinative interactions. Mo₆O₁₉^2- located between two DB₁₈C₆ and led to the formation of the “hamburger” structure. The crystal is stabilized by van der waals force and interaction of π-π system. CCDC: 272936.

Keywords: crown ether polyoxometalates super-molecular compound crystal structure
