A skew trapezoidal bipyramidal coordination geometry based on a C2S4 donor set is found in the structure of (C6H5)2Sn[S2CN(Me)CH2CH2OMe]2, with the SnIV atom lying on a mirror plane.

Two distinct coordination geometries, each based on a C2S4 donor set, are found in the title compounds, being based on an octahedron in (C6H5)2Sn(S2CN(Me)CH2CH2OMe)2 and a skew trapezoidal bipyramid in (C6H5)2Sn[S2CN(CH2CH2OMe)2]2.

The coordination geometry in (n-Bu)2Sn[S2CN(CH2CH2OCH3)2]2, (I), is based on a skewed trapezoidal bipyramid, while that in (C6H5)3Sn[S2CN(CH3)CH2CH2OCH3], (II), is based on a tetrahedron. In the crystal of (I), supramolecular layers parallel to (10-1) are sustained by methylene-C—H⋯O(methoxy) interactions, while in (II), centrosymmetric dimers are formed via pairwise weak phenyl-C—H⋯π(phenyl) contacts.

The metal coordination geometry in each of the title molecules, [Sn(C6H5)3(C8H16NS2)] (I) and [Sn(C6H5)3(C10H12NOS2)] (II), is based on a heavily distorted tetrahedron owing to the asymmetric mode of coordination of the dithiocarbamate ligand. The persence of C—H⋯π(phenyl) interactions in the crystals lead to dimeric aggregates in (I) and supramolecular chains (II).

Heavily distorted trigonal–pyramidal coordination geometries, each based on a C3S2 donor set and with the loosely bound S atom approximately trans to one of the ipso-C atoms, are found in the title compounds (C6H5)3Sn[S2CN(Ben)CH2CH2Ph] and (C6H5)3Sn[S2CN(CH2CH2OMe)2].
