The novel complex tri ( o -chlorobenzyl) tin 3-indolylacetate has been synthesized. The crystal structure of the complex was determined by X-ray diffraction study. The crystal belongs to triclinic system with space group P-1 with a=0.8376(3) nm, b = 1.1118(3) nm, c = 1.6557(5) nm, alpha = 102.747(5)degrees, beta = 101.238(5)degrees, gamma = 107.683(5)degrees, V= 1.4382(8) nm(3), Z=2, D-c= 1.549 g/cm(3), mu(Mo Kalpha) = 11.96 cm(-1), F(000) =674, R-1 = 0.0369, Rw=0.0785; The bond lengths of Sn-C are 0.2143(4), 0.2153(4) and 0.2161(4) nm. The Sn-O is 0.2072(3) nm. The tin atom has a distorted tetrahedral geometry.
