چکیده
The asymmetric unit of the title complex, [Sn(4)(C(4)H(9))(8)(C(11)H(14)NO(2))(4)O(2)], consists of two crystallographically independent half-mol-ecules. The other halves are generated by crystallographic inversion centers. In each tetra-nuclear mol-ecule, both of the two independent Sn atoms are five-coordinated, with distorted trigonal-bipyramidal SnC(2)O(3) 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 SnO(3) trigonal plane. Weak intra-molecular C-H⋯O hydrogen bonds stabilize the mol-ecular structures. In one mol-ecule, two of the butyl groups and the bridging benzoate anion are each disordered over two positions.
