The title compound, [Sn(C6H5)3(C9H10NS2)], has two independent molecules in the asymmetric unit and each features a tetrahedrally coordinated SnIV atom as the dithiocarbamate ligand coordinates in a monodentate fashion. As the non-coordinating thione S atom is proximate to the Sn atom [SnS(thione) = 3.1477 (6) and 2.9970 (5) Å for the independent molecules], distortions from the ideal geometry are evident [the widest angle being 120.48 (5)°]. The most notable feature of the crystal packing is the formation of C—Hπ interactions that lead to the formation of supramolecular layers parallel to (2).

The title compound, [Sn(C4H9)2(C9H10NS2)2], features a tetrahedrally coordinated SnIV atom; the dithiocarbamate ligands coordinate in a monodentate fashion, accompanied by two n-butyl chains. The non-coordinating thione S atoms are each proximate to the SnIV atom [3.0136 (7) and 2.9865 (8) Å], giving rise to distortions from the ideal geometry as evident in the wide C—Sn—C bond angle of 139.06 (12) °. In the crystal, C—HS interactions lead to the formation of a linear supramolecular chain along the b axis. The chains are aligned into layers by C—Hπ interactions, and the layers stack along [001]. One of the ethyl groups is statistically disordered over two sets of sites.

The molecule of the title compound, C15H14N4O3, is completed by the application of crystallographic twofold symmetry, with the carbonyl group lying on the rotation axis. The molecule is close to planar: the greatest deviation of a torsion angle from 0° is 7.3 (2)° about the bond linking the phenol ring to the rest of the molecule. An intramolecular O—HN(imine) hydrogen bond is formed in each half of the molecule. The carbonyl O atom is anti with respect to the amine H atoms and this allows for the formation of N—HO(hydroxyl) hydrogen bonds in the crystal, which results in supramolecular layers lying parallel to (100).
