Structure and magnetic properties of a 3d–4f CoIII2DyIII4 cluster

Four New Families of Polynuclear Zn-Ln Coordination Clusters. Synthetic, Topological, Magnetic, and Luminescent Aspects

“…The second most widespread motif in hexanuclear 3d/4f chemistry is 2,3,4M6–1 (Figures and , bottom). According to a survey in CSD, 33 crystal structures ,,− possess this motif that corresponds to four fused triangles aligned in a plane or forming a twisted boat. The first 3d/4f CCs with this topology can be found in a family of Mn 4 III Ln 2 III compounds where Ln is Gd, Tb, Y, reported in 2008 by Oshi et al Other examples were reported in Mn/4f, ,, Ni/4f, , Co/4f, ,,, and Fe/4f chemistry.…”

“…According to a survey in CSD, 71 33 crystal structures 52,54,81−89 possess this motif that corresponds to four fused triangles aligned in a plane or forming a twisted boat. The first 3d/4f CCs with this topology can be found in a family of Mn 4 III Ln 2 III compounds where Ln is Gd, Tb, Y, reported in 2008 by Oshi et al 81 Other examples were reported in Mn/4f, 54,82,83 Ni/4f, 52,86 Co/4f, 74,84,85,87 and Fe/4f 88 chemistry. Compounds 4−9 are the first examples of the 2,3,4M6−1 motif in Zn II /Ln III chemistry.…”

Synthesis, Characterization, Magnetic Properties, and Topological Aspects of Isoskeletal Heterometallic Hexanuclear CoII4LnIII2 Coordination Clusters Possessing 2,3,4M6–1 Topology

“…More recently four series of Co/Ln III CCs that possess the 2 , 3 , 4M6 – 1 topology have been described. The first example is a Co III 2 Dy III 4 CC based on a ( E )‐2‐[(3‐hydroxypropylimino)methyl]phenol ligand (H 2 L9, Scheme ) showing slow magnetization relaxation . The second example is a family of eight Co III 2 Ln 4 III CCs (Ln is Sm, Pr, Eu, Gd, Tb, Dy, Ho, Er) constructed from ligand HL10 (Scheme ).…”

“…Lanthanide, especially Dy III , and Co II , based, CCs have been widely used to gain access to molecules behaving as single molecule magnets (SMMs). Interestingly, the combination of 3d and 4f ions has been proposed to be an efficient strategy to reach CCs with improved magnetic properties, therefore the synthesis and magnetic properties of Co–Ln CCs has recently received tremendous attention and a plethora of Co–Ln CCs with a variety of nuclearities, Co II 2 Ln III ,, Co II 2 Ln III 2 , Co III 2 Ln III 2 ,, Co II Dy III 3 , Co III 2 Dy III 4 ,, Co II 2 Dy III 4 , Co II 3 Dy III 4 , Co II 2 Dy III 5 , Co II 4 Ln III 4 ,, Co II 6 Ln III , Co II 2 Co III 4 Ln III 4 , Co II 8 Ln III 2 , Co II 2 Dy III 10 , Co II 6 Ln III 8 , Co II 8 Ln III 8 ,, Co II 11 Dy III 6 , Co II 9 Co III Ln III 42 , Co II 16 Ln III 24 , have been reported.…”

A Series of Umbrella‐Shape Copper‐Lanthanides Based Mixed Metallic Coordination Complexes

“…Transition metal – lanthanides(3d–4f) mixed metal complexes have gained increased attention in the recent past due to their exotic applications in the magnetism, fluorescent sensors and catalysis . The most important reason to chemists for continuous synthesis of mixed metal complexes is due to the urge to explore highly interesting magneto‐chemistry such as construction of Single‐molecule magnets (SMMs), magnetic refrigerants, 3D molecule based magnets and single chain magnets .…”
