Tricyclohexyltin 4-amino-3-methyl-benzoate(1) and tricyclohexyltin 3,4-dimethoxybenzoate(2) were synthesized and their crystal structures were determined by X-ray diffraction. Compound 1 belongs to the monoclinic system, space group P21/c with a = 14.0554(15), b = 11.6947(13), c = 16.2720(17) , Z = 4, V = 2565.7(5) 3, Dc = 1.341 g·cm-3, μ(MoKα) = 1.016 mm-1, F(000) = 1080, R = 0.0833 and wR = 0.2964. Compound 2 is of monoclinic system, space group C2/c with a = 17.8712(6), b = 8.4433(3), c = 35.5783(13) , Z = 8, V = 5366.8(3) 3, Dc = 1.360 g·cm-3, μ(MoKα) = 0.980 mm-1, F(000) = 2288, R = 0.0549, wR = 0.1279. In compounds 1 and 2, the central Sn atom is coordinated in a tetradentate manner to assume a distorted tetrahedral configuration. Preliminary biological tests showed that these two compounds have strong acaricidal activity.
