The crystal and molecular structure were determined by X-ray single crystal diffraction. The crystal of the title compound belongs to triclinic, space group P1 with a=1.089 7(3) nm, b=1.050 33(4) nm, c=1.858 5(4) nm, α=96.822(4)°, β=94.477(4)°, γ=94.636(3)°, V=3.001 3(12) nm3, Z=4, Dc=1.679 Mg·m-3, μ(Mo Kα)=1.582 mm-1, S=1.005, F(000)=1 496, R1=0.040 7, wR2=0.076 3. In compound, the tin atom has a distorted tetrahedral coordination configuration. The molecules are packed in one-dimensional chain polymer through a weak interaction between the chlorine atoms from adjacent molecules, respectively. CCDC: 286106.展开更多
