In the title compound, [Cu(C(6)H(10)NS(2))I(C(10)H(8)N(2))], the Cu(II) ion is coordinated by one iodide ion, two N atoms of the bipyridine ligand and two S atoms from the piperidine-carbodithio-ate ligand in a distorted square-pyramidal environment. π-π stacking inter-actions, with centroid-centroid distances of 3.643 (4) Å, between pyridyl rings of the bipyridyl ligands of neighbouring mol-ecules lead to chains propagating parallel to the a axis.
