“…As observed in Figure 2, the Cu 24 -clusters are cuboctahedric units, and the twelve dimers consist of two Cu II square pyramids (SP). The disposition of the twelve dimers is analogous to the cubic close packing of spheres (CCP), but in this 5 case the central position is occupied by a crystallization molecule of water (located at an inversion centre).…”

“…[1][2][3][4][5] In the past decade, great advances have been done in the design, synthesis and characterization of these compounds, 25 despite the difficulties they entail; for instance, the high requirements in crystallographic accuracy. Furthermore, crystal growth is especially relevant in this type of compounds since the principle of maximum space filling in crystal structures often produces outstanding phenomena like interpenetrated 30 frameworks.…”

“…8 Mother structures for Cu24-clusters: HCP-type (compound 2) and CCP-type (compounds 6 and 7). 5 As said before, we have made a special effort in locating the maximum number of molecules of solvent in the structural refinement of compound 1. As a consequence, we have located a molecule of water right in the centre of the cluster.…”

Compound 1 [Cu 24 (m-BDC) 24 (DMF) 20 (H 2 O) 4 ]·24DMF·40H 2 O (m-BDC is 1,3-benzenedicarboxylate and DMF is N,N-dimethylformamide) has been synthesized and structurally characterized by X-ray diffraction. It consists of Cu 24 -clusters arranged in such a way that 12 dimers are connected through m-BDC ligands. The clusters exhibit an internal cavity where crystallization molecules of DMF and water 10 are located. Additionally, there are guest DMF and water molecules in the voids generated by the 3D packing of the Cu 24 -clusters. The thermal stability of compound 1 has been also characterized, concluding that hydrogen bonds between solvent molecules are responsible for the robustness of the network. Compound 1 is similar to other seven compounds found in literature. This work is focused on the crystallochemical comparison of these compounds, which concludes that there are two mother 15 structures related to the hexagonal and cubic close packing of polyhedra, respectively. Derivative compounds are produced by the presence of different solvent molecules (differences affecting both the nature and the number of the guest molecules).

“…This discrete polyhedron is composed of 12 Cu-paddle wheel units that when connected with 24 mBDC linkers produce a truncated cuboctahedron (cuo) with an average cavity diameter of 15 Å (direct distance; without vdW radius) and a volume of 1766 Å 3 . In the same year, this MOP was modified through the use of functionalized mBDC derivatives at its 5-position [65]. This resulted in a family of exteriorly decorated nanoballs that are principally based on the same polyhedron.…”

The Chemistry of Metal-Organic Frameworks: Synthesis, Characterization, and Applications

View full text Add to dashboard Cite

Metal-organic frameworks (MOFs) have attracted enormous scientific interest over the past two decades due to their high crystallinity, exceptional porosity, high modularity, and diverse functionality [1]. The opportunity to achieve functional materials by design with promising properties, unattainable for solid-state materials in general, distinguishes MOFs from any other class of materials, in particular, traditional porous materials, for example, zeolites [2], mesoporous silica [3], and porous carbon [4]. Concepts such as the node and spacer principle [5] are based on simple geometrical analysis, which is facilitated by direct joining of polyhedral or polygonal nodes and linkers to translate their geometry into nets with predictable topology and structure. The obtained crystalline materials represent well-defined structures that allow for studying the design, synthesis, and properties of materials by means of single-crystal X-ray diffraction. Herein, we introduce the concept of secondary building units (SBUs) [1a] as a critical design element for the synthesis of rigid, permanently porous MOFs. Furthermore, the cluster chemistry of copper and zinc is highlighted due to the depth and diversity of their SBU geometries, which allow them to be used in linking with organic units (reticular chemistry) [6]. These will be introduced and exemplified by prominent MOF structures, demonstrating net topologies that have produced numerous functional and expanded frameworks. Secondary Building Units (SBUs): The Design Principles of MOFsIn contrast to molecular building blocks in general [7], which also include single metal nodes, SBUs are defined as an aggregate of metal ions stitched together by multidentate functional groups, such as carboxylates, into clusters (Figure 3.1) [1a]. The SBU term was coined for MOFs as an analogy to SBUs in zeolite chemistry, which are finite or infinite component units that facilitate the structural diversity The Chemistry of Metal-Organic Frameworks: Synthesis, Characterization, and Applications, First Edition.
