The synthesis of the binuclear organotin (Ⅳ) complex [Ph3 Sn (CH3 OH) O2 CC6H4 CO2 (CH3 OH)] using triphenyltin chloride and disodium terephthalate, Its structure was characterized by elemental analysis, FTIR and 1HNMR spectroscopy. X-ray single crystal structure was characterized by X-ray diffraction (XRD), X-ray diffraction The crystal structure of these two compounds was determined by X-ray diffraction. The compound 1 is monoclinic with space group P2 1 / n, a = 1.5199 (5) nm and b = 0.90 0 0 (3) nm. 1.82 0 6 (6) nm, β = 113.970 (5) °, Z = 2, V = 2.2755 (13) nm3, Dc = 1.413g / cm3, μ = 1.146mm-1, F 0 = 980, R1 = 0.0353, and wR2 = 0.0606. Compound 2 is monoclinic with space group P2 1 / c, a = 1.56 6 (5) nm and b = 1.0875 (4) nm, c = 1.35 42 (5) nm, β = 91.6 14 (5) °, Z = 2, V = 2.278 (14) nm3, Dc = 1.498g / cm3, μ = 1.35 1 0,01 = 0,08, R1 = 0,0401, and wR2 = 0,11448. In the crystal of 1 and 2, the tin atom presents a five-coordinate distorted triangular bipyramid configuration. Complex 1 formed a two-dimensional network structure by unhydrogenated methanol molecules through hydrogen bonding
