In the title complex, [Cd(C 6 H 11 N 2 S 2 ) 2 (C 5 H 5 N) 2 ], the Cd II 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 Cd II 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.
