The asymmetric unit of the title complex, [Sn4(C4H9)8(C11H14NO2)4O2], consists of two crystallographically independent half-molecules. The other halves are generated by crystallographic inversion centers. In each tetranuclear molecule, both of the two independent Sn atoms are five-coordinated, with distorted trigonal–bipyramidal SnC2O3 geometries. One Sn atom is coordinated by two butyl groups, one O atom of the benzoate anion and two bridging O atoms, whereas the other Sn atom is coordinated by two butyl groups, two O atoms of the benzoate anions and a bridging O atom. All the butyl groups are equatorial with respect to the SnO3 trigonal plane. Weak intramolecular C—H⋯O hydrogen bonds stabilize the molecular structures. In one molecule, two of the butyl groups and the bridging benzoate anion are each disordered over two positions
