Synthesis, crystal structures and catalytic properties of Ag(I) and Co(II) 1D coordination polymers constructed from bis(benzimidazolyl)butane

Structural modulation of Co(II) coordination polymers with flexible bis(benzimidazole) and different dicarboxylate ligands

“…Among multitudinous organic ligands, benzimidazole-containing ligands, in particular, have proven to be good candidates for the construction of novel MOFs due to their remarkable coordination ability and versatile conformations [7][8][9][10]. To date, some bis(benzimidazole) derivatives such as 1,1-(1,4-butanediyl)bis-1H-benzimidazole, 1,1-(1,4-butanediyl) bis(2-methyl-benzimidazole have been reported in the assembly of preparing such crystalline materials [11][12][13][14][15]. However, MOFs constructed from a flexible 1,3-bis(5,6-dimethylbenzimidazol)propane (L) ligand are relatively scarce, in which 5,6-dimethylbenzimidazole serves as an axial ligand for cobalt in vitamin B 12 [16][17][18][19].…”

Hydrogen Bonds directed 2D→3D Interdigitated Silver(I) Coordination Polymer: Synthesis, Structure, and Catalytic Property

“…After 110 min, about 53.64 % methyl orange is degraded in the case of compound 1 as catalyst (Figure 4), which is little higher than that of [Ag 2 (bbbi) 2 1-(1,4-butanediyl)bis-1H-benzimid-azole, H 2 ntp = 2-nitroterephthalic acid] previously reported by Cui and coworkers. [21] After catalysis, compound 1 displays no obvious structural change, which was verified by the powder X-ray diffraction (Figure 3a), indicating that compound 1 as catalyst can be recycled. In addition, equal molar amount of AgNO 3 was also added into the mixture of methyl orange and Na 2 S 2 O 8 , however, no obvious degradation reaction was observed at the same conditions, which further indicates that compound 1 can serve as a heterogeneous catalyst for degradation of methyl orange.…”

“…According to previously reported literatures, we know that Ag I coordination polymers shows good catalytic activity for degradation of methyl orange. [20,21] Herein, we exploit AgNO 3 , MA and H 2 FA as the starting materials to constructed a new compound, namely [Ag(MA)(FA) 0.5 ] n (1) (MA = melamine, H 2 FA = fumaric acid). It shows a 2D undulated layer structure, which further extends into a 2DǞ3D supramolecular interdigitated framework via intermolecular hydrogen bonds.…”

Investigation on the Synthesis and Photocatalytic Property of Uranyl Complexes of the β-Diketonates Biscatecholamide Ligand

“…Photocatalytic Activity. As we know, methyl blue, methyl orange, and RhB dyes have been widely used in textile, printing, paper, and pharmaceutical industries, causing serious pollution to the environment at the same time [35][36][37][38]. In this work, we selected RhB as model compound of organic pollutant to investigate the degradation efficiency using complexes 1-3 as catalysts.…”
