“…It is well known that multidentate N-heterocyclic compounds form a variety of metal complexes with many intriguing structures and interesting properties. In the last few years, many researchers, including our group, have focused attention on the design and synthesis of metal-organic frameworks (MOFs) based on 2-[(1H-imidazol-1-yl)methyl]-1H-benzimidazole (imb), since it has three potential N-atom donors and can coordinate to metal ions via monodentate, bidentate-bridging or tridentate-bridging coordination modes in the construction of coordination polymers (Yang et al, 2014;Wang et al, 2014). This ligand can also act as a hydrogenbonding donor and acceptor in the assembly of supramolecular structures.…”

Multidentate N-heterocyclic compounds form a variety of metal complexes with many intriguing structures and interesting properties. The title coordination polymer, catena-poly[zinc(II)-bis{μ-2-[(1H-imidazol-1-yl)methyl]-1H-benzimidazole}-κ(2)N(3):N(3');N(3'):N(3)-zinc(II)-bis(μ-benzene-1,2-dicarboxylato)-κ(2)O(1):O(2);κ(3)O(1),O(1'):O(2)], [Zn2(C8H4O4)2(C11H10N4)2]n, has been synthesized by the reaction of Zn(NO3)2 with 2-[(1H-imidazol-1-yl)methyl]-1H-benzimidazole (imb) and benzene-1,2-dicarboxylic acid (H2bdic) under hydrothermal conditions. There are two crystallographically distinct imb ligands [imb(A) and imb(B)] in the structure which adopt very similar coordination geometries. The imb(A) ligand bridges two symmetry-related Zn1 ions, yielding a binuclear [(Zn1)2{imb(A)}2] unit, and the imb(B) ligand bridges two symmetry-related Zn2 ions resulting in a binuclear [(Zn2)2{imb(B)}2] unit. The above-mentioned binuclear units are further connected alternately by pairs of bridging bdic(2-) ligands, forming an infinite one-dimensional chain. These one-dimensional chains are further connected through N-H···O hydrogen bonds, leading to a two-dimensional layered structure. In addition, the title polymer exhibits good fluorescence properties in the solid state at room temperature.

“…21 Bmi displays fluorescence with an emission maximum at 301 nm (λ ex = 270 nm), which corresponds to that reported in the literature. 22,23 Therefore, the emission band of complex 1 may be attributed to intraligand π* ! n transitions within oxalate groups.…”

Two new Cd(II) complexes, {[Cd(COO) 2 ] 2 Á2H 2 O} n (1) and {[CdCl(COO) 2 (Hbmi)]ÁH 2 O} n (2), were obtained through the reactions of oxalic acid (H 2 ox) with CdCl 2 Á2.5H 2 O in the presence of 1-[(benzoimidazol-yl) methyl]-1H-tetrazole (bmt) or 1-[(benzoimidazol-yl)methyl]-1H-imidazol (bmi). Single-crystal X-ray diffraction shows that complex 1 has a 3-D structure with the topological notation of (4 8 Á 62 )(4 6 Á 6 6 Á 8 3 )(4 2 Á 8 4 ), in which the oxalate displays two kinds of coordination modes: formation of the layers (μ 6 -ox) and linking the layers (μ 4 -ox). In complex 2, oxalates bridge Cd(II) ions, forming a 1-D chain, and (Hbmi) + cations coordinate to the Cd(II) ions in monodentate mode and hang at two sides of the main chain. This indicates that subtle modification of the N-donor ligands can result in complexes with different compositions and architectures. Moreover, their IR spectra, PXRD (powder X-ray diffraction) patterns, thermogravimetric analyses, and fluorescence properties are also investigated.
