Crystal structures and Hirshfeld surface analyses of bis­[N,N-bis­(2-meth­oxy­eth­yl)di­thio­carbamato-κ(2) S,S′]di-n-butyl­tin(IV) and [N-(2-meth­oxy­eth­yl)-N-methyl­dithio­carbamato-κ(2) S,S′]tri­phenyl­tin(IV)

The crystal and mol­ecular structures of the two title organotin di­thio­carbamate compounds, [Sn(C(4)H(9))(2)(C(7)H(14)NO(2)S(2))(2)], (I), and [Sn(C(6)H(5))(3)(C(5)H(10)NOS(2))], (II), are described. Both structures feature asymmetrically bound di­thio­carbamate ligands leading to a skew-trapezoidal bipyramidal geometry for the metal atom in (I) and a distorted tetra­hedral geometry in (II). The complete mol­ecule of (I) is generated by a crystallographic twofold axis (Sn site symmetry 2). In the crystal of (I), mol­ecules self-assemble into a supra­molecular array parallel to (10-1) via methyl­ene-C—H⋯O(meth­oxy) inter­actions. In the crystal of (II), supra­molecular dimers are formed via pairs of weak phenyl-C—H⋯π(phen­yl) contacts. In each of (I) and (II), the specified assemblies connect into a three-dimensional architecture without directional inter­actions between them. Hirshfeld surface analyses confirm the importance of H⋯H contacts in the mol­ecular packing of each of (I) and (II), and in the case of (I), highlight the importance of short meth­oxy-H⋯H(but­yl) contacts between layers.
