The structure of the title compound features both bridging and chelating dithiocarbamate ligands, so that a tetragonal pyramidal S
5 coordination geometry results. Each of the chelating ligands is bidentately coordinated to a cadmium atom, and forms a planar four-membered chelate ring [CdS
2C]; However, a pair of tridentate bridging ligands combine two neigbouring cadmium atoms, forming extended eight-membered tricyclic moieties [Cd
2S
4C
2], whose geometry can be approximated by a ‘chair’ conformation. The compound crystallizes in the triclinic space group
P1 with the following unit-cell parameters:
a = 8.5286(6),
b = 11.4221(6),
c = 11.4561(6)Å,
α = 112.632(2),
β = 97.216(2),
γ = 106.241(2)°,
Z = 1. The crystal structure was solved by direct methods using single-crystal X-ray diffraction data collected at room temperature, and refined by full-matrix least-squares procedures to a final
R-value of 0.0297 for 5115 observed reflections. Both of the piperidine rings exhibit a
chair conformation. The structure has an intermolecular hydrogen bond of the type C-H…S, which helps to stabilize the crystal structure.
