A novel supramolecular assembly consisting of sodium-dibenzo-18-crown-6(DB18C6) complex cation [Na(C20H24O6)(CH3CN)(2)](2+) and isopolyanion [Mo6O19](2-) has been demonstrated in the 3D structure of [Na(C20H24O6)(CH3CN)(2)](2)[Mo6O19] center dot 4CH(3)CN (1). Weak intermolecular forces (C-H center dot center dot center dot O hydrogen bonds) between isopolyanion and crown ether play a significant role in the construction of supramolecular framework in the crystal structure of 1. Compound 1 has been characterized in the solid state by single crystal X-ray diffraction, IR, CHN analysis, and TGA.
