The asymmetric unit of the title compound, [Sn(C6H5)2(C12H9N3OS)], contains two independent molecules with almost identical configurations. In each molecule, the SnIV atom is coordinated by O, N and S atoms from a (2-oxido-1-naphthaldehyde)thiosemicarbazonato ligand and two C atoms from phenyl rings in a distorted trigonal-bipyramidal geometry. Weak intermolecular N-HO and N-HS hydrogen bonds link four molecules into a centrosymmetric tetramer. The crystal packing exhibits short intermolecular SS contacts of 3.335 (3) Å.
