| Abstract: The complex of [Na(DB24C8)]3[α-AsMo12O40]·9H2O was synthesized by hydrothermal techniques and cha-racterized by IR and X-ray diffraction analysis. Single crystal X-ray diffraction indicate that this complex is belong to monoclinic, space group P21/n with cell dimension: a=1.480 3(7) nm, b=2.692 7(3) nm, c=3.046 6(4) nm, α=90.00°, β=95.4120(10)°, γ=90.00°. V=12.090 28 nm3, Z=4, F(000)=6 440.0, R=0.050 9, wR2=0.113 5. The crown ethers just coordinate with Na+ and have no direct interaction with the polyoxometalate, because the crown ethers have a contorted configuration. CCDC: 626686. |
