“…In the Fe 2p spectrum, we found that compounds 1 – 4 have peaks at ∼708.0 and ∼720.7 eV, which correspond to Fe II 2p 3/2 and Fe II 2p 1/2 derived from FcDCA 2– , respectively. In 1 and 3 , there are also peaks at ∼712.3 and ∼725.5 eV, corresponding to Fe III 2p 3/2 and Fe III 2p 1/2 , , respectively, which indicate that there are both Fe II and Fe III in 1 and 3 (Figure ). We also analyzed the Cu 2p spectrum, which has ∼934.0 and ∼954.0 eV with two strong satellite peaks.…”

In this work, we synthesized two Cu-based heterometal−oxo clusters 1 and 2 based on M(III) 4 O 4 (M = Fe/ In) cubane centers and obtained the corresponding dimers 3 and 4 by connecting Cu atoms on the cluster cores with the auxiliary ligand 4,4′-bipyridine. They were characterized by single-crystal Xray diffraction (SCXRD), powder X-ray diffraction (PXRD), and other tests. We conducted magnetic property study on compounds 1−4. The variable-temperature magnetic susceptibility test shows that compounds 1 and 3 exhibit significant ferromagnetic interactions at low temperatures, while compounds 2 and 4 exhibit overall antiferromagnetic interactions. When the metal at the cubane changes from magnetic Fe to nonmagnetic In, the magnetic interactions in the compound are weakened to a certain extent. Through dimerization, the extreme values of the variable-temperature magnetic susceptibility appear (1 to 3)/disappear (2 to 4) in the low-temperature section. We investigated the magnetic structure correlation of compounds 1−4 through bond lengths, bond angles, and distances between magnetic atoms. The results showed that compounds 1−4 exhibited significant magnetic coupling diversity.
