An organotin(Ⅳ) complex [(CH3)2Sn(4-FC6H4CONHO)2] has been synthesized and characterized by elemental analysis, IR, 1H NMR and X-ray single-crystal diffraction techni- ques. The crystal belongs to the orthorhombic system, space group Pbca with a = 9.7565(13), b = 17.664(2), c = 20.784(3) , Z = 8, V = 3581.9(8) 3, Dc = 1.695 g/cm3, μ(MoKα) = 1.469 mm–1, F(000) = 1808, R = 0.0321 and wR = 0.0838. In the molecular structure of the title complex, the tin atoms are five-coordinated in a trigonal bipyramidal geometry, and the special coordination properties of dimethyltin(Ⅳ) with hydroxamate-type ligands are also discussed.
