The title compound n-BuO_2CCH_2CH_2SnCl_3 · (2-HOC_6H_4CH = NC_6H_4-OMe-4 ’) was synthesized and characterized by elemental analysis, UV-Vis, IR and 1H NMR. The crystal structure analysis shows that the crystal belongs to the monoclinic space group P2_1 / c, a = 1.4661 (3), b = 0.9307 (2), c = 1.7888 (4) nm and β = 94.04 Mr = 579.45 and Z = 4; V = 2.4348 (8) nm ~ 3; Dc = 1.581 mg / m ~ 3 and μ = 1.405 mm -1; F (000) = 1160; R = 0.0354; Rw = 0.0486. The compound is a monomolecular organotin compound containing an intramolecular carbonyl oxygen coordinate, a Schiff base coordinating with an oxygen atom on a phenolic hydroxyl group, a central six-coordinate tin atom and a distorted octahedral configuration. The synthesis of eight complexes RO_2CCH_2CH_2SnCl_3 · (2-HOC_6H_4CH = NC_6H_4OMe-4 ’) (where R = Me, Et, n-Pr, i-Pr, n-Am, i-Am, Cl-C_2H_4 -, (CH_3CH_2) _2CHCH_2-) were synthesized and characterized. The mechanism of transesterification was proposed.
