Abstract: The crystal structure of the title compound, bis[₂-3-(4-methoxyphenyl)-2-phenyl-2-propenoato]bis[3-(4-methoxyphenyl)-2-phenyl-2-propenoato]di-₃-oxo-tetrakis[dibutyltin(IV)], [Sn₄(C₄H₉)₈(C₁₇H₁₅O₂)₄O₂], is composed of centrosymmetric dimers in which dibutylbis{[3-(4-methoxyphenyl)-2-phenyl-2-propenoato]tin} units containing monodentate and bridging bidentate ligands are coordinated to the central Sn₂O₂ core through its O atoms. Both Sn atoms adopt distorted trigonal bipyramidal geometry, with Sn-C distances lying in a narrow range 2.096  (13)-2.161  (6)  Å, while Sn-O distances range between 2.041  (2) and 2.262  (3)  Å.
