Abstract: The title compound, [CoCl₂(CH₄N₂S)₂].2C₁₁H₆N₂O, consists of the tetrahedral cobalt(II) complex and free 4,5-diazafluoren-9-one (dafone). Dafone links to the complex through hydrogen bonding between N atoms. The carbonyl bridge in dafone distorts the bipyridine moiety. The longer NN separations of 3.068  (3) and 3.064  (3)  Å in dafone are considered to be the reason for the weaker chelating ability of dafone.
