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.
