The complete molecule of the title compound, [Sn(C₄H₉)₂(C₅H₁₀NOS₂)₂], is generated by a crystallographic mirror plane, with the Sn^IVatom and the two inner methylene C atoms of the butyl ligands lying on the mirror plane; statistical disorder is noted in the two terminal ethyl groups, which deviate from mirror symmetry. The dithiocarbamate ligand coordinates to the metal atom in an asymmetric mode with the resulting C₂S₄donor set defining a skew trapezoidal bipyramidal geometry; then-butyl groups are disposed to lie over the longer Sn—S bonds. Supramolecular chains aligned along thea-axis direction and sustained by methylene-C—H...S(weakly coordinating) interactions feature in the molecular packing. A Hirshfeld surface analysis reveals the dominance of H...H contacts in the crystal.

The crystal and molecular structures of two diphenyltin bis(dithiocarbamate)s, [Sn(C₆H₅)₂(C₅H₁₀NOS₂)₂], (I), and [Sn(C₆H₅)₂(C₇H₁₄NO₂S₂)₂], (II), are described. In (I), in which the metal atom lies on a twofold rotation axis, the dithiocarbamate ligand coordinates with approximately equal Sn—S bond lengths and theipso-C atoms of the Sn-bound phenyl groups occupycis-positions in the resulting octahedral C₂S₄donor set. A quite distinct coordination geometry is noted in (II), arising as a result of quite disparate Sn—S bond lengths. Here, the four S-donors define a trapezoidal plane with theipso-C atoms lying over the weaker of the Sn—S bonds so that the C₂S₄donor set defines a skewed trapezoidal bipyramid. The packing of (I) features supramolecular layers in theabplane sustained by methylene-C—H...π(Sn–aryl) interactions; these stack along thec-axis direction with no specific interactions between them. In (II), supramolecular chains along theb-axis direction are formed by methylene-C—O(ether) interactions; these pack with no directional interactions between them. A Hirshfeld surface analysis was conducted on both (I) and (II) and revealed the dominance of H...H interactions contributing to the respective surfaces,i.e. >60% in each case, and other features consistent with the description of the molecular packing above.

The crystal and molecular structures of the two title organotin dithiocarbamate compounds, [Sn(C₄H₉)₂(C₇H₁₄NO₂S₂)₂], (I), and [Sn(C₆H₅)₃(C₅H₁₀NOS₂)], (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)viamethylene-C—H...O(methoxy) interactions. In the crystal of (II), supramolecular dimers are formedviapairs 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.

The crystal and molecular structures of two triphenyltin dithiocarbamates, [Sn(C₆H₅)₃(C₁₆H₁₆NS₂)], (I), and [Sn(C₆H₅)₃(C₇H₁₄NO₂S₂)], (II), are described. In (I), the dithiocarbamate ligand coordinates the Sn^IV atom in an asymmetric manner, leading to a highly distorted trigonal–bipyramidal coordination geometry defined by a C₃S₂ donor set with the weakly bound S atom approximately trans to one of the ipso-C atoms. A similar structure is found in (II), but the dithiocarbamate ligand coordinates in an even more asymmetric fashion. The packing in (I) features supramolecular chains along the c axis sustained by C—H...π interactions; chains pack with no directional interactions between them. In (II), supramolecular layers are formed, similarly sustained by C—H...π interactions; these stack along the b axis. An analysis of the Hirshfeld surfaces for (I) and (II) confirms the presence of the C—H...π interactions but also reveals the overall dominance of H...H contacts in the respective crystals.

The crystal and molecular structures of two triphenyltin dithiocarbamate compounds,viz. [Sn(C₆H₅)₃(C₈H₁₆NS₂)], (I), and [Sn(C₆H₅)₃(C₁₀H₁₂NS₂)], (II), are described. The dithiocarbamate ligand in each molecule coordinates in an asymmetric fashion resulting in heavily distorted tetrahedral C₃S coordination geometries for the Sn atoms, with the distortions traced to the close approach of the non-coordinating thione-S atom. The molecular packing in both compounds features C—H...π(Sn-phenyl) interactions. In (I), the donors are Sn-phenyl-C—H groups leading to centrosymmetric aggregates, while in (II), the donors are both Sn-phenyl-C—H and methyl-C—H groups leading to supramolecular chains propagating along thebaxis. The identified aggregates assemble into their respective crystals with no directional interactions between them. An analysis of the Hirshfeld surfaces show distinctive patterns, but an overwhelming predominance (>99% in each case) of H...H, C...H/H...C and S...H/H...S contacts on the respective Hirshfeld surface.
