Abstract: | A novel cobalt–carboxylate framework constructed from secondary building units (SBUs), {Co16(btca)8(H2O)40]·16H2O}n (1) (H4btca = 1,2,3,4-butanetetracarboxylic acid) has been hydrothermally synthesized and characterized by techniques of single-crystal X-ray diffraction analyses, elemental analyses, infrared spectra, powder X-ray diffraction and thermogravimetric analyses. The complex exhibits 2D 4-connected sql net with (44 × 62) topology symbol built from Co2(COO)4(H2O)5] SBUs and is further extended into a 3D supramolecular architecture via strong O–H···O hydrogen bonds. Moreover, the magnetic measurements indicate complex 1 exhibit antiferromagnetic behavior. |
