Experimental Crystal data

disorder in main residue; R factor = 0.031; wR factor = 0.078; data-to-parameter ratio = 12.8. In the title compound, [Co(C5HF6O2)2(C9H8N2)], the Co II centre exhibits a pseudooctahedral coordination geometry, comprising two N-atom donors from the bidentate amino-quinoline ligand and four O-atom donor atoms from two bidentate chelating 1,1,1,5,5,5-hexafluoropentane-2,4-dionate ligands. In the crystal, molecules are linked via pairs of N— H O hydrogen bonds, forming inversion dimers. These dimers are further connected through – interactions between neighbouring quinoline rings [centroid–centroid distance = 3.472 (2) Å], and stack along the c axis. Related literatur
