“…There are many reasons for the continuing interest in the synthesis and study of multinuclear 3d molecular metal clusters (Koumousi et al, 2013). In particular, clusters containing Mn III , Fe III , Co II and Ni II usually show fascinating structures and attractive magnetic properties, exhibiting high-spin (S) ground-state values and single-molecule magnetic (SMM) behaviour (Aromi & Brechin, 2006).…”

A new tetranuclear mixed-valence cobalt complex, namely di-μ2-azido-diazidodiethanolbis{μ2-2-[(hydroxyimino)methyl]-6-methoxyphenolato}bis{μ3-6-methoxy-2-[(oxidoimino)methyl]phenolato}dicobalt(II)dicobalt(III) ethanol disolvate, [Co(II)2Co(III)2(C8H7NO3)2(C8H8NO3)2(N3)4(C2H5OH)2]·2C2H5OH, has been synthesized by the reaction of Co(OAc)2·4H2O (OAc is acetate) with 3-methoxysalicylaldoxime (H2mosao) in an ethanol solution. In the complex, the four Co cations all display distorted octahedral coordination environments and they are bridged by two κ(2),κ(1),κ(1);μ3-mosao(2-) ligands, two κ(2),κ(2);μ2-Hmosao(-) ligands and two μ2-N3(-) anions to form a tetranuclear [Co4N4O4] cluster. Adjacent clusters are connected through weak C-H···N and C-H···O interactions, resulting in a two-dimensional supramolecular network parallel to the ac plane. The magnetic properties of the complex have also been studied.

“…Thus, there is indeed further potential to explore and prepare more iso-POT precursors utilized for the preparation of iso-POM-based derivatives. What is more, the combination of iso-POT building blocks with as-synthesized TM/RE clusters (for instance, {Fe 10 }, {Fe 12 }, {Ag 20 } and {Dy 10 }) may also be an efficient way to obtain high-nuclear nanosized iso-POT-based derivatives (Koumousi et al, 2013;Li et al, 2018;Westin et al, 2003), which has already been confirmed by Fang's illuminating work on the assembly of the magnetic cluster {Mn 14 W 48 } (Fang & Luban, 2011).…”

Recent advances in isopolyoxotungstates and their derivatives

et al. 2018

During the past decade, isopolyoxotungstates (iso‐POTs) and their derivatives have been greatly developed due to their unique structures and potential applications in luminescence, magnetism, catalysis etc. This brief review is principally focused on the main research progress on iso‐POTs, iso‐POT‐based transition‐metal derivatives, iso‐POT‐based rare‐earth derivatives, iso‐POT‐based organometallic derivatives and iso‐POT‐based heterometallic derivatives, and gives a summary of some representative examples of their syntheses, structures and related properties. In addition, an outlook on the future of this area is presented in the final section. We believe that this systematic commentary on iso‐POTs and their derivatives will not only disclose a rich set of iso‐POT structures, but also reveal a more promising direction for the further functionalization of iso‐POTs.
