A new compound [Cu4 (H2O) 8 (L) 4 was synthesized from 3,5-pyridinedicarboxylic acid (L), cupric nitrate and ammonium metatungstate using the method of room temperature aqueous solution synthesis ] 3 (H5W12O40) 4 · 12H2O. The compound was characterized by elemental analysis, thermogravimetric analysis, infrared spectroscopy and X-ray single crystal diffraction. The results show that the compound belongs to the cubic system, I23 space group; a = b = c = 2.532 6 (5) nm, α = β = γ = 90 °, V = 16.244 (6) nm3, Z = 2, R1 = 0.0408, wR2 = 0.096 9.
