“…Indeed, there are many distinct examples of such pcu-MOFs, due to the exceptional tunability of this platform. It is possible to substitute the original Cu 103,108,110,125,129,131,137,140 from the SBL with other metals, such as Zn, 102,104-106,108,110-119, 122-126,130,132,133,135,136,138,142-157 Ni, 109,127,139 Co, 107,120,121,134,139,141,158,159 Mn, 160 Fe, 128 Cu/Zn, 125 etc., but also to vary the length (1,4-BDC, 105,107,109,110,113,118,[121][122][123][124][125][126]128,132,135,142,143,[145][146][147][148][149]160 2,6-NDC, [103]…”

In this review, we describe two recently implemented conceptual approaches facilitating the design and deliberate construction of metal–organic frameworks (MOFs), namely supermolecular building block (SBB) and supermolecular building layer (SBL) approaches. Our main objective is to offer an appropriate means to assist/aid chemists and material designers alike to rationally construct desired functional MOF materials, made-to-order MOFs. We introduce the concept of net-coded building units (net-cBUs), where precise embedded geometrical information codes uniquely and matchlessly a selected net, as a compelling route for the rational design of MOFs. This concept is based on employing pre-selected 0-periodic metal–organic polyhedra or 2-periodic metal–organic layers, SBBs or SBLs respectively, as a pathway to access the requisite net-cBUs. In this review, inspired by our success with the original rht-MOF, we extrapolated our strategy to other known MOFs via their deconstruction into more elaborate building units (namely polyhedra or layers) to (i) elucidate the unique relationship between edge-transitive polyhedra or layers and minimal edge-transitive 3-periodic nets, and (ii) illustrate the potential of the SBB and SBL approaches as a rational pathway for the design and construction of 3-periodic MOFs. Using this design strategy, we have also identified several new hypothetical MOFs which are synthetically targetable.

“…In contrast to the dicopper molecules described in Section 3.1, only a few manganese paddlewheel structures have been reported in the literature. The first metal-organic framework (MOF) with a manganese paddlewheel core was published in 2008 by Fu et al [44] In the work of these authors, the MnÀMn distance is 3.06 . The same MnÀMn distance was found in our UMP2 optimization of the anhydrous manganese formate.…”

Magnetic Properties of Paddlewheels and Trinuclear Clusters with Exposed Metal Sites

Magnetic exchange-coupling constants of tri- and dinuclear transition-metal complexes (paddlewheels) have been computed using various ab initio methods. The di- and trinuclear complexes under study may serve as secondary building units in metal-organic frameworks (MOFs). Multi-reference methods such as the complete-active-space self-consistent-field method (CASSCF) as well as second-order perturbation theory (CASPT2) yield spin ladders from which the magnetic exchange-coupling constants are obtained. For the dicobalt paddlewheels, inclusion of spin-orbit coupling is crucial for obtaining a qualitatively correct description of the system. Density functional theory (DFT) was applied in the framework of the broken-symmetry approach using single- and double-hybrid functionals as well as generalized-gradient-approximation (GGA) functionals. The computed magnetic exchange-coupling constants are compared with experimental and other theoretical data, where available.

“…Thus, it is often employed as a bridging ligand to construct porous frameworks. Based on terephthalate, there are many interesting examples of polymeric solids that present novel structural topologies with open framework structural features, such as plywood-like network [14], square grid [8,13,[15][16][17], brickwall [18,19], honeycomb [20,21], and other frameworks [12,[22][23][24][25][26][27][28][29]. On the other hand, the utilization of template molecules provides more opportunities for exploring frameworks with desirable topologies and architectures since they influence the crystal packing.…”
