Abstract: The title compound, [Sn₄O₂(C₇H₂ClN₂O₆)₄(C₄H₉)₈], is a centrosymmetric dimer of an oxoditin(IV) complex. Two dibutylbis[4-chloro-3,5-dinitrobenzoate]tin(IV) units containing monodentate and bridging bidentate carboxylate ligands are connected to the central Sn₂O₂ core. Each Sn atom adopts a distorted trigonal-bipyramidal geometry, with Sn-C distances lying in the narrow range 2.119 (3)-2.135 (3) Å, while Sn-O distances range between 2.037 (2) and 2.286 (2) Å.
