A new ionic crystal Synthesis and crystal structure of ionic crystal: K2NaH[Cr3O(OOCCH3)6(H2O)3][α-CoW12O40]·10H2O has been synthe- sized characterized by single crystal X- ray diffraction, IR spectra, elemental analysis, Thermogravimetric analysis (TGA). Crystal data: monoclinic C2/c, a = 4. 190 5(8) nm, b = 1. 615 8(3) nm, c = 2. 983 4(6) nm,β= 123.67(3)°, V= 16. 812(6) nm^3, Z = 14, F(000) = 13 200, RI = 0. 076 3, ωR2 = 0. 142 7. The polyanion and macrocation clusters stacked alternately through electrostatic interactions as well as the coordination of Na^+ and K^+ and form a novel three-dimention porous microstructure,oppositely charged cluster ions packed alternately to form one - dimensional channels with dimension of about 1.31 nm × 1.09 nm.
