摘要：

Three metal-organic frameworks,{[Mg2（MFDA）2（DMF）3]·0.5H2O}_n（1）,{[Ca（MFDA）(DMF)（H2O）]·0.5DMF}_n（2）and[Ca（MFDA）(DMF)2]_n（3）(DMF=N,N-dimethylformamide)have been synthesized by the solvothermal reactions between the ligand 9,9-dimethylfluorene-2,7-dicarboxylic acid（H2MFDA）and the corresponding metal salts,respectively.The single crystal X-ray structural analyses reveal that compounds 1-3 display three-dimensional structures based on the M（Ⅱ）-O-C chains.It is interesting that the MFDA ligands in 1-3 have different dihedral angles between the two carboxylate groups ranging from 9.9（1）°to 41.8（2）°.All of compounds exhibit strong ligand-centered blue emissions under UV lights.Their thermal properties have also been studied.
