Abstract:A new compound(C2H10N2) H3As3O10] was synthesized under mild hydrothermal conditions.The product was characterized by means of infrared spectrometry,X-ray powder diffraction,thermogravimetry,and single-crystal X-ray diffraction.Results show that the product belongs to monoclinic,space group P2(1)/n,with cell parameters a = 0.808 3(6) nm,b = 1.446 9(9) nm,c = 0.892 0(8) nm,β = 98.16°,V = 1.032 7(14) nm3,Z = 4,F(000) = 864,R1 = 0.025 3,and wR2 = 0.093 4.Its empirical formula is C2H13As3N2O10,and its molecular weight Mr = 449.90.It is the first example of arsenate with one-dimensional chain structure supported by organic cations,whose adjacent arsenate chains are packed along c axis through AAAA manner,forming three-dimensional topological structure.
Keywords:chain-like arsenate  hydrothermal synthesis  crystal structure
