Tributyltin 4-picolinate was synthesized by the reaction of tributyltin chloride with sodium 4-picolinate and characterized by IR, 1HNMR and MS. The X-ray single crystal diffraction indicated that the compound belongs to the monoclinic system with space group P2_1 / c, α = 9.667 3 (14), b = 23.845 (4), c = 9.707 (14) A; °, F (000) = 848, R_1 = 0.054 4, ωR_2 = 0, V = 2 067.9 (5) A, Z = 4, Dc = 1.324 Mg m -3, μ = 1.242 mm -1, 0.141 1. The compounds are bridged by the nitrogen atom of 4-picolinic acid ligand to form a one-dimensional infinite chain polymer with five-coordinate trigonal bipyramid configuration.
