The title complex, [Sn4(C4H9)8(C7H3ClNO4)4O2], is a cluster formed by a crystallographic inversion center around the central Sn2O2 ring.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 procharger for ram 1500 5.7 hemi the other Sn atom is coordinated by two butyl groups, two O atoms of the benzoate anions and a bridging O atom.

The O atoms of the bridging benzoate anion are disordered over two sites with an prolock fittings occupancy ratio of 0.862 (12):0.138 (12).

One of the butyl groups coordinated to the Sn2O2 ring is disordered over two sites with an occupancy ratio of 0.780 (8):0.220 (8), whereas both of the two butyl groups coordinated to the other Sn atom are disordered over two sites with occupancy ratios of 0.

788 (5):0.212 (5) and 0.827 (10):0.

173 (10).All the butyl groups are equatorial with respect to the SnO3 trigonal plane.In the crystal, complex molecules are stacked down [010] with weak intermolecular C—H.
