Two new coordination compounds [Co(FDC)₂(H₂O)₂]_n (1) and [Cu(FDC)₂(2,2΄-bpy)]·DMF·H₂O (2) (HFDC = 9-fluorenone-4-carboxylic acid, bpy = 2,2΄-bipyridine, DMF = N,N-dimethylformamide) were prepared by the reactions of corresponding metal salts with a fluorene derivative ligand of HFDC. Both compounds were thoroughly analyzed by X-ray single-crystal diffraction, elemental analysis, IR spectra, PXRD and thermal analysis. Compound 1 features a 1D structure. Via two kinds of O‒H···O hydrogen bonds, such 1D chains self-assemble into a 3D supramolecular structure stabilized by the offset face-to-face π···π interactions. Compound 2 features a dinuclear structure which, via O‒H···O and C‒H···O hydrogen bonds, self-assembles into a 2D supramolecular layer strengthened by strong face-to-face π···π interactions. And variable-temperature magnetic susceptibilities of 1 and 2 indicate weak antiferromagnetic interactions between the Co(II) and Cu(II) metal ions.
