The novel complex tri(o-chlorobenzyl)tin ferrocenecarboxylate have been synthesized. The crystal structure of the complex has been determined by X-ray diffraction. The crystal belong to orthorhombic with space group Pbca with a = 0.1242(5), b = 1.7242(7), c = 3.0583(13) nm, V = 5.928(4) nm3, Z = 8, Dc = 1.623g · cm-3, μ (MoKα) = 0.1631 cm-1, F(000) = 2896, R1 = 0.0461, wR2 = 0.0931. The bond lengths of Sn-C is 0.2148(4), 0.2152(6) and 0.2176(5)nm, respectively. The Sn-O is 0.2073(4) nm. The tin atom has a distorted tetrahedral geometry. The ...
