The crystal structure of K2NaH [Cr3O (OOCCH3) 6 (H2O) 3] [α-CoW12O40] .10H2O was synthesized and its crystal structure was characterized by X-ray single crystal diffraction, elemental analysis, infrared spectroscopy and solid-state diffuse reflectance electron spectroscopy. The crystal belongs to the monoclinic system. The C2 / c space group has a = 4.190 5 (8) nm, b = 1.615 8 (3) nm, c = 2.983 4 (6) nm and β = 123.67 = 16.812 (6) nm3, Z = 14, F (000) = 13 200, R1 = 0.076 3, wR2 = 0.142 7. In this crystal structure, the oppositely charged polyanion clusters and the large cation clusters alternate in space Arranged in a three-dimensional open structure with one-dimensional pores by ion bonding and weakly coordinating bonds of counter ions K + and Na +, and the pore size is 1.31 nm × 1.09 nm.
