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 [Sn...S(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—H...π inter­actions that lead to the formation of supra­molecular layers parallel to (\overline{3}2\overline{1}).

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—H...S inter­actions lead to the formation of a linear supra­molecular chain along the b axis. The chains are aligned into layers by C—H...π inter­actions, and the layers stack along [001]. One of the ethyl groups is statistically disordered over two sets of sites.

In the title compound, C11H12N4S, the thio­phene ring is roughly planar, with a maximum deviation of 0.012 (1) Å for the S atom, and makes a dihedral angle of 7.89 (8)° with the mean plane of the piperidine ring, which is in a chair conformation. The crystal packing is stabilized by pairs of centrosymmetric inter­molecular N—H...N hydrogen bonds, which results in the formation of a step-wise chain parallel to [10\overline1].

In the title compound, C12H14N2OS, the pyrrolidine ring adopts an envelope conformation with the C atom at the 3-position as the flap and makes a dihedral angle of 65.80 (9)° with the benzene ring. In the crystal, N—H...O hydrogen bonds join c-glide related mol­ecules into chains extended along [001] that are further connected into (100) layers via C—H...O inter­actions.
