Abstract: Bright-blue crystals of the centrosymmetric title compound, [Cu(C₂N₃)₂(C₁₁H₆N₂O)₂], were obtained by reacting copper(II) chloride with 4,5-diazafluoren-9-one (dafo) and sodium dicyanamide. X-ray diffraction analysis reveals that the dicyanamide and dafo ligands are bonded to the Cu atom to give a distorted octahedral geometry. The dicyanamide anions are terminally bonded in trans postitions. Weak C-HO and C-HN interactions help to define the crystal packing.
