The title compound ((CH3CH2CH2CH2NH3)2SnBr6, Mr = 746.44) has been syn- thesized by hydrothermal technique and its crystal structure was determined by X-ray diffraction method. It crystallizes in monoclinic, space group P21/m with a = 10.633(2), b = 7.6152(15), c = 12.633(3) ?, β = 103.25(3)°, V = 995.7(4) ?3, Z = 2, Dc = 2.490 g/cm3, F(000) = 692, μ(MoKα) = 13.309 mm-1 and T = 293(2) K. The final R = 0.0634 and wR = 0.1236 for 936 observed reflections with I > 2σ(I). Each tin atom in the present compound is coordinated by six bromine atoms to adopt a slightly distorted octahedral geometry. The interactions between protonated organic amine and [SnBr6]4- anions are electrostatic. The thermogravimetric analysis shows that the compound is not decomposed until 260 ℃. The optical absorption spectrum of the compound reveals the appearance of a sharp optical gap of 2.95 eV, and fluorescence study shows it displays intense blue emission in solid state.
