✦ Synopsis
The title compound, C~8~H~12~Cl~2~N~2~O~2~, contains two half-molecules in the asymmetric unit. The complete molecule is generated by inversion symmetry in both cases.

The molecule of the title compound, C~26~H~26~N~2~, sits on a center of symmetry such that the two naphthalene ring systems are in an __anti__ conformation with respect to one another across the piperazine ring. An intermolecular π–π interaction between the naphthalene ring systems is observed.
In the title complex, [Sn(C~7~H~6~Cl)~2~(C~7~H~13~N~2~S~2~)Cl], the Sn atom is five-coordinate in a trigonal–bipyramidal geometry. One Sn—S bond is markedly longer than the other for the chelating dithiocarbamate ligand.
The molecule of the title compound, [Sn(C 2 H 5 ) 2 (C 11 H 12 N 3 -O 2 S 2 )Cl], features an asymmetrically chelating thiocarboxylate ligand. The Sn atom is five-coordinate within a C 2 ClS 2 donor set that is best described as trigonal bipyramidal with S and Cl atoms in axial positions, defining a
