The two organotin 4-iodobenzoates, Ph3Sn(p-I-C6H4O2) (1) and {[n-Bu2Sn(p-I-C6H4O2)](2)O}(2) (2) have been synthesized by the reaction of triphenyltin hydroxide and dibutyltin oxide with 4-Iodobenzoic acid in ethanol and benzene, respectively. IR, H-1 NMR, Elemental analysis and X-ray diffraction for the title complexes were presented. The crystal of complex 1 belongs to triclinic, space group P (1) over bar. The tin atom has a distorted tetrahedral geometry and the dimeric structure is formed by intermolecular hydrogen bonds and C-I center dot center dot center dot pi. The crystal of complex 2 belongs to monoclinic, space group C2/c. The dimer structure is shaped by one Sn2O2 planar four-membered ring and one-dimensional coordination polymer chain is formed by intermolecular I center dot center dot center dot I interaction. The thermal gravimetric analysis has showed that: the complexes 1 and 2 are stable below 230 degrees C. It is found that the inhibitory activity of compounds 1 and 2 on weeds A maranthus spinosus and Portulaca oleracea are greater than the effect on crop mung bean, and inhibitory activity of the compound 2 is higher than 1. It provides a method to study the herbicide for Amaranthus spinosus and Portulaca oleracea. CCDC: 1039846, 1; 1039847, 2.
