“…Hence the crystal of 1 is a H-bonded 3D-framework. It should be noted that the referred hydrogen bonds are charged-assisted, which are generally one of the strongest, wherein the H-bond donor and/or acceptor carry positive and negative ionic charges respectively [39][40][41][42][43].…”

“…Water molecules serve as donors and negatively charged sulfonate and carboxylate groups serve as acceptors among these charge-assisted H-bonds. Such charge-assisted H-bonds are found to be stronger than H-bonds formed between neutral atoms and are known to play crucial role in supramolecular assemblies [46][47][48][49][50][51][52]. A strong intramolecular hydrogen bond is formed due to the hydrogen atom in hydrogen maleate anion (HMA) and because of this hydrogen bond the anion exists in a bent conformation making it topologically very similar to the disulfonate ligand.…”

Two new 1D coordination polymers [Pr(1,3-BDS)(HMA)(H 2 O) 4 ] n and [Er(1,3-BDS)(HMA)(H 2 O) 4 ] n (1,3-BDS = benzene-1,3-disulfonate and H 2 MA = maleic acid) having one-dimensional zigzag polymeric structure and containing praseodymium and erbium in ?3 oxidation state were synthesized by solution synthesis method. The compositions and structures of coordination polymers were determined by elemental analysis, FT-IR, X-ray diffraction, and results of thermal decomposition. Coordination polymers [Pr(1,3-BDS)(HMA)(H 2 O) 4 ] n and [Er(1,3-BDS)(HMA)(H 2 O) 4 ] n are isomorphous and contain distorted square antiprism geometry around metal ion. Two molecules of benzene-1,3-disulfonate and hydrogen maleate coordinate to each metal ion in unidentate bridging mode to generate a linear zigzag polymeric chain. Four water molecules are also coordinated to each metal ion. Hydrogen bonded interaction involving water molecules, carboxylate and sulfonate groups of adjacent polymer chains lead to two-dimensional polymer expansion. The polymers are thermally robust as is indicated by thermal studies. Graphical abstract

“…Gil-Hernandez et al [78,97] prepared the L/D-metal configured homochiral MOFs 2D-[Ln 2 (μ-dhm) 3 (H 2 O) 6 ] (Ln ¼ La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Er, Yb) by using achiral chelating and bridging dhm 2À ligand through self-resolution during crystallization. All the compounds are all isostructural and crystallize in the space group R32.…”

Chiral metal-organic frameworks (MOFs) have attracted much attention, not only due to their potential applications in enantioselective separation and catalysis, but also because of many advantages such as the high density of active catalytic centers, high level of porosity, regular and reliable crystalline nature, and relatively easy immobilization as compared to other heterogeneous systems. As metal-connecting nodes of MOFs, a large number of chemical synthetic strategies have focused on the transition metal ions which exhibit specific coordination geometries and restricted stereochemistry in the past two decades. However, the researches on chiral lanthanide MOFs are still limited up to now because of high coordination numbers, kinetic lability, weak stereochemical preference, and more variable nature of the coordination sphere for lanthanide ions. In this chapter, we would give a brief introduction to highlight the synthetic approaches reported and the structural features of chiral lanthanide MOFs or coordination polymer, which may be beneficial to explore structurally and functionally defined chiral solid materials.
