Two novel complexes μ-chlorine-tribenzltin (1) and μ-oxygen-tribenzltin (2) with the one-dimensional infinite were synthesized. The crystal structures of compounds were determined by X-ray diffraction. The crystal of (1) belongs to Orthorhombic space group P212121 with a=0.855 3(3), b=1.081 4(4), c=1.968 1(7) nm, V=1.820 4(11) nm3, Z=4,Dc=1.560 g·cm-3, μ(Mo Kα)=15.47 cm-1, F(000)=856, R1=0.059 7, wR2=0.141 5. The crystal of (2) belongs to Orthorhombic space group P212121 with a=1.982 3(4), b=1.089 1(2), c=0.861 1(17) nm, V=1.859 0(6) nm3, Z=4, Dc=1.458 g·cm-3, μ(Mo Kα)=13.76 cm-1, F(000)=820, R1=0.032 7, wR2=0.064 8. The tin atoms in the crystal structures rendered five-coordinate in a distorted trigonal bipyramidal configurations. CCDC: 274181, 1; 274182, 2.
