摘      要：Two new coordination compounds[Co(FDC)_(2)(H_(2)O)_(2)]_(n)(1)and[Cu(FDC)_(2)(2,2?-bpy)]·DMF·H_(2)O(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 *** compounds were thoroughly analyzed by X-ray single-crystal diffraction,elemental analysis,IR spectra,PXRDand thermal *** 1 features a 1D *** two kinds of O?H···O hydrogen bonds,such 1Dchains self-assemble into a 3D supramolecular structure stabilized by the offset face-to-faceπ···π*** 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-faceπ···π*** variable-temperature magnetic susceptibilities of 1 and 2 indicate weak antiferromagnetic interactions between the Co(II)and Cu(II)metal ions.
