Controlling self-assembly of zinc(II)-benzoate coordination complexes with 1,4-bis(4-pyridyl)ethane by varying solvent and ligand-to-metal ratio: Their catalytic activities

Anion Effects on Crystal Structures of CdIIComplexes Containing 2,2'-Bipyridine: Photoluminescence and Catalytic Reactivity

“…15,16 Therefore, many efforts have been devoted to the study of fundamental structural aspects to understand and control the several factors that affect the self-assembly of supramolecular architectures. There are several factors affecting the supramolecular assemblies, such as the coordination geometry of metal ions, 17 [44][45][46][47][48] and template effect. 49 Among them, the anions play a very important role on the self-assembled construction.…”

Design and characterization of silver(I) azide coordination polymers based on 1,2-bis(4-pyridyl)ethane and phenazine

“…Much effort has been paid to crystal engineering of coordination polymers due to their fascinating structures as well as potential applications in material science such as catalysis, magnetism, molecular sieves, luminescence, electrical conductivity, chirality, sensors and gas storage [1][2][3][4][5]. Although a wide variety of coordination polymers with interesting structures and properties have been reported, it is still a great challenge to control the motifs and dimensionality of coordination polymers as the formation of these polymers is influenced by many factors including coordination geometry of the metal, the organic ligand (functional, steric and electronic properties), the solvent system, the metal-to-ligand ratio, the template and the counter anion (size and coordinating ability).…”

Metal-directed assembly of metal(II) benzoates (M = Mn, Ni, Co, Cu, Zn, and Cd) with 1,2-bis(4-pyridyl)ethene: Light- and photo-induced [2 + 2] cycloaddition

“…Carboxylate-including ligands have been used to form coordination polymers due to their various coordination modes and bridging ability [2], and bipyridyl ligands have been commonly used as two-connecting linear bifunctional spacers [1,2,6,7,14]. In addition, acetate and trifluoroacetate have been efficiently utilized to orient the C=C bonds of trans-1,2-bis(4-pyridyl)ethene (bpe) ligands in ladder coordination polymers for photo-dimerization reactions [15].In our efforts to investigate the control of the self-assembly of functional supramolecular complexes with intriguing structures and potential applications in catalysis, we have recently carried out a systematic study of zinc metal-organic complexes from the mixed-ligand systems of multifunctional organic ligand benzoate and bridging ligands such as pyrazine, its derivatives [16], and 1,2-bis(4-pyridyl)ethane [17]. Moreover, the influence of the metal ion effects was also investigated from the reaction of various metal-benzoates with a rigid ligand 4,4′-bipyridine (4,4′-bpy) [18] and a bridging flexible ligand 1,2-bis(4-pyridyl)ethane (bpa) [19].…”

Importantly, the assembly process of metal-benzoates and bipyridyl ligands has been highly influenced by solvent system [17], pH [20], metal-to-ligand ratio [17], and the coordination geometry of metal ions [19].…”
