【Abstract】 Thirty - two title complexes ROCOCHR1CH2SnCl3 (2 - HOC6H4CH = NC6H4 - X) (R = Me, Et, n - Bu; R1 = H, Me; X = H,4’ - Cl, 3’ - Br, 3’ - OH, 3’, 4’ - Cl2, 4’ - OMe) were synthesized and characterized by elemental analysis , UV - vis , IR , 1 H NMR . The crystal structure of n - BuOCOCH2CH2SnCl3 (2 - HOC6H4CH = NC6H4OMe - 4’) were determined by the X-ray diffraction analysis. The crystal belongs to monoclinic system, with a = 1.4661 (3)nm, b =0.9307(2)nm, c = 1.7888(4)nm, β = 94.04(3)°, V = 2.4348nm3, Dc = 1.581mg/m3, Z = 4, F(000) =1160, ,μ = 1.405mm-1, R= 0.0354, Rw = 0.0486. space group: P21/c.The complexes exist as a discrete monomer. The tin atom has a distorted octahedral geometry due to intramolecular coordination of the carbonyl oxygen and the phenolic oxygen of the Schiff base ligands. The coordination number of tin atom is 6.更多还原
