Large Magnetocaloric Effect in a Wells–Dawson Type {Ni₆Gd₆P₆} Cage

CuII Frameworks from Di‐2‐pyridyl Ketone and Benzene‐1,3,5‐triphosphonic Acid

“…To this end, and in the context of exploring new functional materials, phosphonate-based coordination polymers and MOFs have attracted tremendous interest due to their unique structural features and potential applications in various fields, including ion exchange, [6,15] catalysis, [16] adsorption and separation, [16] proton conductivity, [17] water treatment, [15,18] biotechnology, [15,16] photochemistry, [19] dental medicine, [16] cancer treatment, [16] bone disease treatment, [20] magnetism [16,21] and magnetic refrigeration. [22][23][24] It has been proven that the structural variability of metal phosphonates can be increased by the introduction of auxiliary ligands that can coordinate to the metal ions. A number of metal phosphonates exist that are derived from the combination of phosphonates and other ligands.…”

A 48‐Metal Cluster Exhibiting a Large Magnetocaloric Effect

“…First, the isotropic electronic configuration of Gd 3+ affords multiple low-lying excited spin states, while the disparate d n /f 7 electronic configurations offer the possibility of a large-spin ground state as long as the nuclearity of the cluster is sufficiently high. [3,4] Second, a high-nuclearity cluster complex with small ligands naturally leads to a large metal/ligand mass ratio. [7] In constructing high-nuclearity 3d-4f cluster complexes, self-assembly of the metal ions has been remarkably successful.…”

“…Compound 1 was obtained from the reaction of Gd-(NO 3 ) 3 , Ni(CH 3 COO) 2 , and NaCl in ethanol/water. Singlecrystal X-ray diffraction studies revealed a tubelike cationic cluster (Figure 1) and two Cl À ions that are confined inside the tube.…”

“…[13] . This assembly is templated by a NO 3 À ion that is hydrogen-bonded to six m 3 -OH À groups (four O···HÀO 3.004(11) , O···HÀO 155.688; two O···HÀO 3.001(12) , O···HÀO 155.788) along the inner rim of the wheel. NO 3 À ions acting as templates have been reported in 3d-4f metal clusters.…”

Magnetocaloric effect in gadolinium-oxalate framework Gd2(C2O4)3(H2O)6⋅(0⋅6H2O)

“…1 Its use through the adiabatic demagnetization process has first focused on low temperatures. [2][3][4] Different kinds of materials have attracted interest for their MCE in low temperature region (2-4 K), including simple paramagnetic salts, 4,5 molecular nanomagnets, [6][7][8][9][10][11][12] extended porous networks, 13 garnets, 14 or intermetallic alloys. 15 For a more exhaustive insight, two recent review articles dealing with coordination compounds 16 or molecule-based 17 magnetic coolers can be consulted.…”
