The title compound, [Cd(NCS)2(C12H8N2)2], has been obtained from the decomposition reaction of dithiooxamide in a dimethylformamide solution containing 1,10-phenanthroline (phen) and Cd(NO3)2·4H2O. Its crystal structure is formed by monuclear CdII entities in which the metal atom is sited on a twofold rotation axis. The CdII atom is six-coordinated in the form of a distorted octahedron by two chelating phenanthroline molecules and two thiocyanate anions coordinated through their N atoms. In the crystal, C—H⋯N hydrogen bonds are established between the phenanthroline and thiocyanate ligands of neighbouring complexes.
