Title: Syntheses, structures and properties of three metal–organic complexes containing 2,2′-dipyridyl-5,5′-dicarboxylate ligands

Abstract

Three new metal–organic complexes Cu[Hbpdc]{sub 2} (1), [Ni(bpdc)(H{sub 2}O)]·H{sub 2}O (2) and [Ni(H{sub 2}bpdc)(H{sub 2}O){sub 2}]SO{sub 4} (3) (H{sub 2}bpdc=2,2′-bipyridyl-5,5′-dicarboxylic acid) have been hydrothermally prepared and structurally characterized by elemental analyses, IR spectra, powder X-ray diffraction (PXRD) and single-crystal X-ray diffraction. 1 is a 3-D supramolecular architecture formed by hydrogen bonding interactions between carboxyl O atoms and strong face-to-face π⋯π stacking interactions between bipyridyl rings of Hbpdc{sup −} ligands, 2 exhibits an intriguing 2-D sheet constructed from [Ni(bpdc)(H{sub 2}O)] units and 3 displays an infinite 1-D chain built by ([Ni(H{sub 2}bpdc)(H{sub 2}O){sub 2}]{sup 2+}) fragments through SO{sub 4}{sup 2−}. Moreover, thermogravimetric (TG) and derivative thermogravimetric (DTG) analyses of 3 have been conducted and the TG curve shows two-stage weight loss between 300 and 950 K and the corresponding apparent activation energies are calculated by Ozawa–Flynn–Wall (OFW) method and Friedman method. The most probable kinetic model function of the dehydration reaction of 3 has been estimated by Coats–Redfern integral method and Achar–Bridly–Sharp differential method. - Graphical abstract: Three metal–organic complexes containing 2,2′-dipyridyl-5,5′-dicarboxylate ligands were synthesized and the thermal decomposition kinetics were investigated. - Highlights: • Metal–organic complexes containing 2,2′-dipyridyl-5,5′-dicarboxylate ligands. • 3-D supramolecular architecture. • Thermal decomposition kinetics.
