Charge Neutral [Cu2L2] and [Pd2L2] Metallocycles: Self-Assembly, Aggregation, and Catalysis

“…The self-assembly of complex metallosupramolecular architectures from simple metal and organic components − has yielded a range of interesting and intricate structures with a wide range of applications. − These structures can be polymeric or discrete and often display unusual topologies and properties that are not present in their constituent building blocks . They have been shown, for example, to display a wide range of guest-binding, catalysis, and storage/separation uses. ,− The design of the building blocks that are programmed to assemble into these architectures plays a crucial role in determining both the form and function of the resulting metallosupramolecular complexes. It has been shown that ligands incorporating multiple β-diketone groups can be reacted with certain metal ions to form a series of metallosupramolecular structures with a significant degree of predictability. ,− The resulting structures include helicates, , tetrahedra, − and interlocked assemblies, , as well as stimuli-responsive and exceptionally porous polymeric systems. , …”

A novel Fe3O4@TCH@Ni(II) nanoparticle: An efficient magnetically retrievable nanocatalyst for C–C and C–heteroatom bond formation reaction

“…[20,22] But, in the last decades, several reports have been published on using different transition metals such as Cu, Ni, Co, Fe, and Pd as catalysts to crosscoupling reactions. [23,24] In this field, Suzuki, [25] Heck, [26] and Sonogashira [27] all of them are the well-known reactions. More recently, a variety of magnetic core-shell Fe 2 O 3 @CSF@Cu, [28] Fe 3 O 4 @boehmite-NH 2 -Co(II)-NPs, [29] and Fe 3 O 4 @SiO 2 -EDTA-Ni(II) [24] nanocomposites have been rapidly developed as efficient, inexpensive, sustainable nanocatalysts for cross-coupling reaction.…”

Intrinsic Effect of Pyridine-N-Position on Structural Properties of Cu-Based Low-Dimensional Coordination Frameworks

“…Coordination complexes containing ambidentate ligands that are capable of binding metal-ion centres in more than one way through different donor-atom combinations provide an efficient strategy in the construction of functional coordination assemblies [ 12 , 13 ].Of the many structurally distinct ambidentate ligands, pyridyl-β-diketonates have been widely employed in the generation of different coordination systems from simple mononuclear complexes, [ 14 ] through cages [ 15 ] and macrocycles [ 16 ] to larger architectures (e.g., polymers (CPs) and metal-organic frameworks) [ 15 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ] Importantly, coordination structures based on ambidentate ligands have shown real potential in many applications including catalysis, [ 24 , 25 , 26 ] bioinorganic modelling [ 27 , 28 ] and molecule magnetism [ 29 , 30 , 31 ] and in the design of molecular machines [ 32 ]. More recently, ambidentate ligands have been successfully utilized with metal ions such as Pd(II), Pt(II) and Cu(I) to provide a series of metallosupramolecular complexes with different levels of dynamicity and high catalytic activity in important processes such as the Suzuki–Miyaura, alkene hydrosilylation and Ullmann reactions [ 24 , 25 , 26 ].…”
