In the title compound, [Sn2(C4H9)4(C6H6PO3)4]n, the basic unit is a dimer containing two symmetry-related SnIV atoms bridged by two hydrogenphenylphosphonate anions. This fragment is located about an inversion center, and each SnIV atom is linked to two other hydrogenphenylphosphonate anions, giving a layered structure parallel to (010). The coordination geometry for the SnIV atoms is close to octahedral. The layers are connected via O—H
O hydrogen bonds, generating a three-dimensional network. One butyl group is disordered over two sets of sites, with occupancies of 0.49 (2) and 0.51 (2).

The asymmetric unit of the binuclear title compound, [Sn2(C2O4)(C6H5)6(CH4N2S)2], consists of one half of the organotin(IV) molecule. The remainder is generated by a twofold rotation axis passing through the mid-point of the oxalate C—C bond. The SnIV atom exhibits a distorted trigonal–bipyramidal coordination environment with the phenyl groups in equatorial positions and the thiourea and the monodentately bridging oxalate anion in axial positions. The molecules are linked through N—HO hydrogen bonds involving the amino group of the thiourea ligand and the uncoordinating oxalate O atoms, forming layers parallel to (001). Weak C—HO interactions are also present.
