Abstract: A one dimensional compound (NH3CH2CH2NH3)AgAsS4 with ladder like chains was synthesized solvothermally. This compound crystallizes in the monoclinic system, space group C2/c , with a =1 358 05(8)nm, b =0.653 31(3)nm, c =2.277 11(9)nm, β =106.42(3)°, Z =8. The compound comprises anionic chains formed by tetrahedral AsS4 sharing apices with AgS3, and organic cations are located between the chains. The hydrogen bonding of N—H…S exists in the compound, which together with electrostatic force hold the anionic chains together.

Key words: Solvothermal synthesis, Polynary thioarsenate, Crystal structure
