| Abstract: A super-molecular complex, [Na(DB18C6)(CH3CN)]2W6O19·(CH3CN)2, was obtained by solvothermal reaction and characterized by IR , 1H NMR, gumbc spectrum single crystal and X-ray diffraction. The compou- nd crystallizes in monoclinic space group P21/c with a=1.185 22(4) nm, b=2.091 51(8) nm, c=1.487 19(5) nm, β=117.467(2)° and Z=2. The complex contains four basic units: Na+, CH3CN, DB18C6 and W6O192-. 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 W6O192- via the coordinative interactions. W6O192- located between two DB18C6 and led to the formation of the “hamburger” structure. Two isolated CH3CN are included in the complex. The whole title crystal is stabilized by van der waals force. CCDC: 292369. |
