Synthesis, Crystal Structures, and Catalytic Properties of Silver(I) and Cobalt(II) Coordination Polymers Based on Flexible Bis(benzimidazole) with Pyridine‐2, 6‐Dicarboxylate

Abstract

Two coordination polymers, [Ag 2 (pydca)(bbbi) 2 ] n (1) and [Co 2 (pydca) 2 (bbbi) 3 ] n ·nH 2 O (2) [pydca = pyridine-2,6-dicarboxylate, bbbi = 1,1Ј-(1,4-butylene)bis-1H-benzimidazole)] were hydrothermally synthesized and characterized by elemental analysis, IR spectroscopy, TG, PXRD, and single-crystal X-ray diffraction. Compound 1 features a one-dimensional helical chain structure bridged by bbbi

Synthesis, Structures, and Catalytic Properties of Two Silver(I) Coordination Polymers Constructed from 1,4-Bis(benzimidazolyl)butane

“…The free bbbm ligand displays luminescence with an emission maximum at 368 nm upon excitation at 350 nm, which can be assigned to π → π * transitions [24,25]. Peaks at about 371 and 436 nm are found in the emission spectra of 1 and 2 when they are excited at 336 and 338 nm, respectively.…”

Synthesis, Crystal Structure, Luminescent and Photocatalytic Properties of a Cd(II) Coordination Polymer with (3, 6)-Connected rtl Topology

“…During the self-assembly process, many unpredictable factors, such as reaction temperatures, co-ligands, solvents, templates and so on, may influence the final structures [10][11][12][13]. It have been well documented that judicious selection of appropriate organic ligands and metal ions plays an important role in achieving the expected coordination polymers with the desired structures and promising properties [14,15]. Among the various types of organic ligands, organic polycarboxylate ligands are often used to fabricate coordination polymers owing to their strong coordination abilities and versatile coordination modes [16][17][18].…”

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

“…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.…”
