A novel silver (I) coordination polymer [Ag(BIM)ClO4 ] n (BIM =bis(imidazol-1-yl)-methane) has been synthesized and characterized in the solid state by X -ray diffraction.It crystallizes in a monoclinic space group P2(1)/c, with a =4.8952(4), b =14.1094(13), c =15.5731(14) ?,α=90,β=90.458(2),γ=90 °, V =1075.57 (16) ?3 , Z =4, Dc=2.195 mg/m 3 ,μ=2.132 mm-1 , F(000) =696, the final R=0.0302 and wR=0.0762 for 1814 observed reflections with I >2σ(I).It contains one -dimensional zig -zag cationic chains formed through BIM and AgI . And the three-dimensional frameworks were formed by metal -πinteractions and bridged perchlorate anions .TGA measure-ment suggests that it is thermal stability with the decomposition temperature at 352℃.
