Homo- and heterometallic coordination polymers from the f elements

Abstract

Lanthanide and actinide based coordination polymers and metal-organic framework materials present a number of interesting opportunities with respect to their syntheses and properties. Ln elements typically display large coordination numbers and roughly spherical bonding environments whereas An elements (specifically U(VI)) tend to form triatomic species with terminal oxo groups. As such, these features may be perceived by some as obstacles to the development of designed architectures of f-metal containing hybrid materials. We argue that these features, when coupled to the luminescent behavior of these elements actually give rise to a diverse family of compounds with a range of interesting topologies. Presented herein is an overview of the structural features and luminescent behavior of these materials, as well as some synthetic strategies toward producing both homo-and heterometallic compounds.

Synthesis, Structure, and Thermal Stability of Supramolecular Polymers with 1D Chain: [M(BPP)2(TBTLiu1, Gao2, Lv3 et al. 2012International Journal of Inorganic Chemistry0000View full textAdd to dashboardCite

“…Rational design and preparation of supramolecular polymers have attracted considerable attention owing to their potential applications in optics, magnetism, adsorption, ion exchange, catalysis, and so forth [1][2][3][4][5][6][7]. In principle, the most effective approach for producing such metal-organic supramolecular polymers is primarily dependent on the rational choice of the organic-bridging ligands as well as the metal ions [8][9][10][11][12][13].…”

“…Different from 4,4 -bipyridine and its derivatives, 1,3-bis(4-pyridyl)propane is flexible and can adopt different conformations characterized due to the aliphatic chain between the two pyridine rings. In view of the bridging and blocking function of the 2,3,5,6-tetrabromoterephthalic acid (H 2 TBTA) and 1,3-bis(4-pyridyl)propane (BPP) ligands, therefore, in this paper, we have been assembled two supramolecular polymers [M(BPP) 2 …”

Preparation of a Novel Nano-scale Lead (II) Zig-Zag Metal–Organic Coordination Polymer with Ultrasonic Assistance: Synthesis, Crystal Structure, Thermal Properties, and NBO Analysis of [Pb(μ-2-pinh)N3 H2O]n

“…Numerous factors affect the assembly of these coordination polymers, such as the coordination configuration of metal ions, geometric characteristics of organic ligand spacers, metal-ligand ratios, solvents, counter-anion characteristics and reaction conditions [3][4][5][6][7]. Because of their economic, environmental and biological roles, the selective sensing and chelation of toxic heavy metals such as Pb(II), Cd(II), and Hg(II) is very important.…”

Structural Isomers of a Potential Linking Ligand Containing a Pyridyl and a Carboxylate Terminals: (n-py)-CH=N-C6H4-CH2-COOH} (n = 3, 4)

“…[13][14][15][16][17][18][19][20][21] We also recently prepared several pyridyl-carboxylate-type linking ligands (L1-L6 in Chart 1) and their coordination polymers. [22][23][24][25][26][27][28][29][30][31] Ligands L1 and L2 contain an amide (-C(O)-NH-) fragment, whereas ligands L3-L6 possess an imine (-C=N-) fragment.…”
