(NH3CH2CH2 NH2) 3 [PW12 O40] · 1 1H2O was reported for the first time by means of hydrothermal synthesis. The crystal structure was confirmed by elemental analysis, IR spectroscopy, thermogravimetric analysis and X-ray single crystal diffraction. The structural analysis showed that: The crystal belongs to the monoclinic space group P2 1 / n with unit cell parameters of a = 1.8559 (4) nm and b = 1.351 3 (3) nm, c = 2.04 4 1 (4) ) nm, β = 95.6 (3) °, V = 5.1 0 3 (2) nm3, Z = 4, R1 = 0.0775, wR2 = 0.9554
