| Popis: | 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. |
