In the title complex, [Fe(NCS)2(C11H8ClN3)2], the FeII atom is coordinated by two N atoms from the thio­cyanate ligands and four N atoms from two chelating 5-chloro-2-(phenyl­diazen­yl)pyridine ligands, generating a fairly regular FeN6 octa­hedral coordination geometry. The thio­cyanate ions are in a cis disposition and the pyridine N atoms are in a trans orientation. In the crystal, a short inter­molecular Cl⋯S contact [3.366 (3) Å] is observed.
