{4-[(3-Formyl-4-hy-droxy-phen-yl)diazen-yl]benzoato}triphenyl-tin.

In the title compound, [Sn(C(6)H(5))(3)(C(14)H(9)N(2)O(4))], the Sn atom has a distorted tetra-hedral geometry with one of the carboxyl-ate O atoms and the C atoms from three phenyl groups. The other carboxyl-ate O atom of the benzoate ligand inter-acts weakly with the Sn atom, with an Sn⋯O distance of 2.790 (2) Å, which causes a distortion of the tetra-hedral coordination geometry.
