The title compound, [Sn(C6H5)2Cl2(CH4N2S)2], has been obtained from the reaction between Sn(C6H5)2Cl2 and SC(NH2)2. The asymmetric unit consists of one half of the mol­ecular unit, the remainder generated by a twofold rotation axis located along the Cl—Sn—Cl bonds. The SnIV atom is coordinated by two phenyl groups, two Cl atoms and two thio­urea ligands in an all trans octa­hedral C2Cl2S2 environment. Individual mol­ecules are connected through N—H...Cl hydrogen bonds, leading to a three-dimensional network structure. Intra­molecular N—H...Cl hydrogen bonds are also present.

In the title compound, [N(C4H9)4][Sn(C4H9)Cl4], the SnIV atom of the stannate anion has a trigonal-bipyramidal coordination sphere by two Cl atoms and one butyl chain in the equatorial plane and by two Cl atoms in the apical positions. Two of the four butyl chains of the tetra­butyl­ammonium cation are partially disordered, each with refined site occupancies of 0.691 (6):0.309 (6). Weak C—H...Cl hydrogen-bonding inter­actions help to consolidate the crystal packing, as well as a short Cl...Cl inter­action of 3.295 (2) Å.
