In the centrosymmetric title compound, [Cd2(C13H12NOS2)4], pairs of dithiocarbamate ligands exhibit different structural functions. Each of the terminal ligands is bidentately coordinated to one CdII atom and forms a planar four-membered CS2Cd chelate ring, whereas pairs of the tridentate bridging ligands link two neighbouring CdII atoms, forming extended eight-membered C2S4Cd2 tricyclic units whose geometry can be approximated by a chair conformation. The coordination polyhedron of the CdII atoms is a distorted square-pyramid. The five-membered furan ring and the benzene ring are disordered over two sets of sites with an occupancy ratio of 0.62 (8):0.38 (8).

The Ni2+ ion in the title complex, [Ni(C3H5OS2)2(C6H4N2)2], is in a strongly distorted octahedral coordination environment formed by an N2S4 donor set, with the Ni2+ ion located on a centre of inversion. In the crystal, weak C—HS and C—HN interactions are observed.

In the title complex, [Cd(C6H11N2S2)2(C5H5N)2], the CdII ion is hexacoordinated by two N atoms from two pyridine ligands and by four S atoms from two dithiocarbamate ligands in a distorted octahedral geometry. The CdII ion lies on a twofold axis. The piperazine ring is in chair conformation and its least-squares plane makes a dihedral angle of 81.4 (1)° with that of the pyridine ring.

The title compound, C9H12ClN4+·Cl−, is a natural metabolic product of imidacloprid [systematic name: (E)-1-(6-chloro-3-pyridylmethyl)-N-nitroimidazolidin-2-ylideneamine] and was obtained by the reduction of the latter using Fe in HCl. The dihedral angle between the pyridine and imidazole rings is 62.09 (12)°. The crystal structure is stabilized by N—HCl and C—HCl interactions involving the chloride anion. The pyridine N and the chloride atoms are not involved in intermolecular interactions.
