“…And the decarboxylation of H 2 pydc to pdc was further suggested based on elemental analysis, IR, and structural analysis. In the light of several reported cases, 67,68 it appears that electron-withdrawing groups are conducive to the rupture of carbon−carbon bonds during the carboxyl decarboxylation process. The N atom in H 2 pydc is considered as an electron-withdrawing group, and the coordination of N atom with Cu ion in compound 1 enhances the electron-withdrawing ability of the N atom, which promotes the decarboxylation of H 2 pydc.…”

Organic rigid ligand-modified polyoxometalate-based materials possess complex and diverse structures, promising electrochemical energy storage properties and outstanding photocatalytic capabilities. Hence, two new [BW 12 O 40 ] 5− (abbreviated as {BW 12 O 40 })-based inorganic-organic hybrids [{Cu(en) 2 (H 2 O)}][{Cu(pdc)(en)}{Cu(en) 2 }(BW 12 O 40 )]•2H 2 O (1) and [{Cu I 5 (pz) 6 (H 2 O) 4 }(BW 12 O 40 )](2) (pdc = 2-picolinate, en = ethylenediamine, pz = pyrazine) were successfully synthesized through a hydrothermal method. Among them, pdc and pz were obtained by in situ transformation from 2,6-pyridinedicarboxylic acid (H 2 pydc) and 2,3-pyrazinedicarboxylic acid (H 2 pzdc), respectively. In compound 1, the {BW 12 O 40 } clusters as an intermediate junction connect with {Cu(pdc)(en)}{Cu(en) 2 } and {Cu(en) 2 (H 2 O)} to form monomers, which in turn form supramolecular chains, sheets, and space network via hydrogen bonding. The {BW 12 O 40 } clusters are packed into copper-pyrazine frameworks in compound 2, and a unique polyoxometalate-based metal organic frameworks (POMOFs) structure with a new topology of {12} 2 {6.12 3 .14 2 } 2 {6 2 .12.14 2 .18}{6 2 .12 3 .16}{6} 6 is formed via covalent bonds. When used as electrode materials for supercapacitors, the values of specific capacitance are 651.56 F g −1 for 1-GCE and 584.43 F g −1 for 2-GCE at a current density of 2.16 A g −1 and good cycling stability (90.94%, 94.81% of the initial capacity after 5000 cycles at 15.12 A g −1 , respectively). The kinetic analysis reveals that surface capacitance plays a major role. Furthermore, both compounds can effectively degrade Rhodamine B (RhB) and Methylene blue (MB), showing the outstanding photocatalytic performance.

“…Also, it possesses both rigidity and flexibility, because of the free rotation of two benzene rings around the bridged nonmetallic atom. Furthermore, it can act as an hydrogenbond acceptor as well as donor (Wu et al, 2008;Wang et al, 2011a). Using the semirigid V-shaped multicarboxylate ligand with the help of secondary ligands: bpy and bbi ( Fig.…”

Two new interesting entangled structures, namely, [Ni1.5(L)(bpy)2(H2O)3]n · 3nH2O (I) and [Cd3(L)2(bbi)2]n · nH2O (II) (where H3L is 4-(4-carboxyphenoxy)-phthalic acid, bpy is 4,4 -bipyridine, and bbi is 1,1 -(1,4-butanediyl)bis(imidazole)) have been synthesized and characterized by elemental analysis (EA), infrared spectra (IR), X-ray powder diffraction (XRPD), solid fluorescence and thermogravimetric analysis (TGA). Single-crystal X-ray diffraction analysis revealed that complex I possesses a 3D self-penetrating framework constructed from ladder-like and fishbone-like subunits. Complex II shows a 3D framework of two-fold interpenetration assembled from trinuclear Cd(II) clusters bridged by bbi and L 3− ligands.

Some supramolecular H 2 oba and 4,4 0 -bpy complexes with diverse topologies have been synthesized, their coordinated cations are Ag(I) [18], Cu(II) [19,20], and Co(II) [21]. Polymeric H 3 pimdc complexes are not many.…”

The reactions of dicarboxylic acids, such as 4,4-oxybis(benzoic acid) [H 2 oba] and 2-propyl-4,5-imidazoledicarboxylate [H 3 pimdc], under hydrothermal conditions in the presence of an appropriate zinc salt yield two mononuclear complexes, which are characterized by elemental analysis, infrared spectrum, electrochemical analysis, thermal analysis, and X-ray crystal diffraction. Complex 1, [Zn(Hoba) 2 (4,4 0 -bpy) 2 ], forms a 2-D supramolecular layer like rhombus via hydrogen bonds (O-H Á Á Á N). Complex 2, [Zn(H 2 pimdc) 2 (2,2 0 -bpy)] Á H 2 O, forms a zig-zag chain via multiple hydrogen bonds and C-H Á Á Á interactions. The moderate hydrogen-bond interactions in 1 and 2 play an important role for structural stability. The electrochemical analyses of 1 and 2 reveal electron transfer of 1 is reversible and 2 is quasi-reversible.
