Fourteen new diorganotin carboxylates were synthesized by the condensation of diorganotin oxide and substituted-ferrocenyl carboxylic acid. The structures of the products were determined by H NMR, IR and elemental analysis. The struture of compound 12 was determined by X-ray crystallography analysis. The molecule is centrosymmetric dimer and has a core of Sn-2O-2 unit. The endocyclic Sn atoms exist in a distorted triginal bipyramidal geometry with the coordination number of 5. The exocyclic Sn atoms form 6 significant bonds and exist in a distorted octahedron geometry. The results of antitumor tests showed that some of the products have high inhibiting activity for KB ceUs and Bel-7402 cells.
