| Abstract: The tri(o-methylbenzyl)tin chloride (1) and the bis(p-methylbenzyl)tin dichloride (2) have been synthesized. The crystal structures of the complexes were determined by X-ray diffraction. The crystal 1 belongs to Rhombohedral space group R3 with a=1.329 36(8) nm, b=1.329 36(8) nm, c=2.147 0(3) nm， α=β=90°, γ=120°, V=3.285 8(5) nm3, Z=6, Dc=1.424 g·cm-3, μ(Mo Kα)=12.93 cm-1, F(000)=1 428, R1=0.037 1, wR=0.110 2. The crystal 2 belongs to Monoclinic space group C2/c with a=2.850 4(3) nm, b=0.491 23(5) nm, c=1.215 32(12) nm, β=112.517(2)°, V=1.5719(3) nm3, Z=4, Dc=1.690 g·cm-3, μ(Mo Kα)=19.49 cm-1, F(000)=792, R1=0.038 0, wR2=0.109 4. The tin atoms have a distorted tetrahedral coordination geometry. CCDC: 606931, 1; 6066932, 2. | |||||||||||||||
