A potential ferromagnetic lanthanide‒transition heterometallic molecular‒based bacteriostatic agent

Three Gd-based magnetic refrigerant materials with high magnetic entropy: From di-nuclearity to hexa-nuclearity to octa-nuclearity

“…The metallic Gd III ions (Gd1 and Gd1A) are surrounded by two L 2 - ligands using the aforementioned mode, two NO 3 − anions and two H 2 O molecules located above and below the plane, respectively. The average bond lengths of Gd-O and Gd-N are 2.379 (5) Å and 2.460 (5) Å ( Supplementary Table S1 ), respectively, which are in accordance with those of the reported Gd-based complexes ( Chen et al, 1995 ; Zhao et al, 2017 ; Mayans and Escuer, 2021 ; Ren et al, 2021 ). In complex 1 , the Gd ion is seven-coordinated to form a capped trigonal prism, which is confirmed by CShM calculations ( Alvarez et al, 2005 ; Casanova et al, 2005 ) ( Supplementary Figure S1 , Supplementary Table S4 ).…”

“…The Gd1, Gd2, Gd3, Gd5, and Gd6 ions are in {O 6 N 2 } environment with six O atoms and two N atoms from two chelated L 2ligands, one CO 3 2anion and one CH 3 OH/H 2 O molecule, which display a biaugmented trigonal prism configuration (Supplementary Figure S2). The average Gd-O and Gd-N distances are 2.352 (4) Å and 2.475 (4) Å, respectively (Supplementary Table S2), which are consistent with those reported Gd-based complexes (Chen et al, 1995;Zhao et al, 2017;Mayans and Escuer, 2021;Ren et al, 2021).…”

“…The average Gd-O distance is 2.361 (4) Å, which is shorter than that of Gd-N (2.564 (4) Å) lengths. The O/N-Gd-O/N angles are in the range of 60.99 °-154.86 °, which are in the normal range (Chen et al, 1995;Zhao et al, 2017;Mayans and Escuer, 2021;Ren et al, 2021).…”

Lanthanide induced variability in localised CoII geometries of four triangular L3Co3IILnIII complexes

“…1–8 While mononuclear and homometallic polynuclear complexes are among the most common, there is a great interest in heterometallic complexes with predictable nuclearities and topologies. Heterometallic polynuclear complexes have been explored in many fields of science from antibacterial agents 9–11 and molecular machines, 12–15 to heterogenous catalysts, 16–19 molecular magnets, 20–25 and spintronic devices. 26–30…”

Heterometallic polynuclear complexes have been explored in many elds of science from antibacterial agents [9][10][11] and molecular machines, [12][13][14][15] to heterogenous catalysts, [16][17][18][19] molecular magnets, [20][21][22][23][24][25] and spintronic devices. [26][27][28][29][30] A hexa-phenolate macrocycle, templated with an all-in-plane tetranuclear Zn 3 LaO 6 3d/4f core, was rst reported by Nabeshima.…”
