An Inorganic Helix [Mn(IPG)(MeOH)]n[PF6]n[‡]: Structural and Magnetic Properties of asyn-anti Carboxylate-Bridged Manganese(II) Chain Involving a Tetradentate Ligand

Syntheses, Crystal Structures, and Magnetic Properties of Novel Manganese(II) Complexes with Flexible Tripodal Ligand 1,3,5-Tris(imidazol-1-ylmethyl)-2,4,6-trimethylbenzene

“…Assuming the coupling interaction between Mn 1 and the pentanuclear is taken into account as zj ‘ and z = 2, the mole magnetic susceptibility of 2 will be The best fitting by Matlab in the range of 300K to 5 K gives g = 2.04, J 1 = −0.43 cm -1 , J 2 = −0.41 cm -1 , and zj ‘ = −0.092 cm -1 with R = 6.40 × 10 -4 . The results indicate the oxalate bridges and the carboxylate in syn−anti coordination mode mediate weak antiferromagnetic coupling between Mn II ions in 2 , which is comparable with those reported previously …”

Chain, Pillar, Layer, and Different Pores: AN-[(3-Carboxyphenyl)-sulfonyl]glycine Ligand as a Versatile Building Block for the Construction of Coordination Polymers

“…In 3 and 4 , coupling J arises from the syn−anti carboxylate bridge and gives a weak antiferromagnetic coupling in this case. It is comparable to those reported for other Mn(II) species with similar carboxylate bridges . The results presented above confirm that the carboxylate bridges generally favor weak interactions.…”

Ferrocenyl-based di- and trinuclear lanthanide complexes: solid state structures, (spectro)electrochemical and DFT studies

“…The lanthanide contraction (radii: Sm > Eu > Gd > Tb) results in a constant decrease of Ln-O bonds (Table 2) exemplarily explained by their bond lengths towards the aqua ligand (Ln-O8) decreasing via 2.462(4) (2) > 2.441(2) (3) > 2.422 (3) (4) > 2.403(2) Å (5), which is in accordance with reported values. 37,38 The sole exception to this trend is the κ 2 mode of O1.…”
