An inorganic-organic hybrid thioantimonate(Ⅲ) [CH3(CH2)3NH3]2Sb4S7 1 with layered structure was synthesized by solvothermal method. 1 crystallizes in the triclinic system,space group P1 with a=7.0124(11),b=11.919(2),c=14.879(3),α=108.791(3),β=102.441(3),γ=92.846(2)o,V=1140.1(3)3,Mr=859.71,Z=2,Dc=2.504 g/cm3,μ =5.324 mm-1,F(000)=804,S=1.013,the final R=0.0297 and wR=0.0618 for 3534 observed reflections with I > 2σ(I). 1 consists of [C4H9NH3]+ cations and two-dimensional [Sb4S7]n2n- anion which is composed of three SbS3 trigonal pyramids and one SbS4 unit joined by sharing common corners. The anionic layers are stacked perpendicularly to the c axis of the unit cell forming two-dimensional channels between the layers. The [C4H9NH3]+ cations interdigitate in a bilayer and reside in the 2D channels leading to a sandwich-like arrangement of the anion and cations.
