Abstract: 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).
