A functionalized polyoxometalate by hexanuclear copper–amino acid coordination complexes

Lanthanide-Incorporated Borotungstates Including Keggin-type [BW11O39]9– Fragments and Their Luminescence Properties

“…When it comes to TMSPs based on {BW 11 } fragments, it is noteworthy that Ritchie et al reported the first photochromic BT-based diarylethene coordination complex [(C 25 H 16 N 2 F 6 S 2 )­(BW 11 O 39 Co) 2 ] 12– in 2018, which was made by connecting two cobalt­(III)-incorporated [BW 11 O 39 Co] 6– segments with pyridyl-containing diarylethene . Wang and co-workers combined copper–amino acid cations with {BW 12 } units and obtained chiral three-dimensional (3-D) frameworks with helical channels. , To our knowledge, acidification of {BW 11 } in the presence of tungstate not only can generate {BW 12 } but also can form other derivatives such as {BW 13 } that are derived from Keggin-type undecatungstic anion capped by a μ-oxoditungstic {W 2 O 11 } group. − It was not until 2013 that Reinoso et al managed to obtain an Fe III -substituted BT derivative [{Fe­(H 2 O) 3 } 2 (WO 2 )­(HBW 11 O 39 ) 2 ] 8– , which is an unparalleled 2-boro-23-tungstate unit stabilized by Fe 3+ ions at external positions, delegating the first TM substitution in the {BW 13 } framework . Currently, a lot of TM-containing BTs have been reported by varying BT building units or changing TM species. − However, related reports on Ln-substituted BTs (LnSBTs) are underdeveloped.…”

Chirality Induction in Crystalline Solids Containing Sandwich-type [Ln(α2-P2W17O61)2]17– Polyoxotungstates and Proline

“…Polyoxometalates (POMs) are regular aggregates of corner-, edge-, and face-sharing polyhedra composed of metal atoms such as W, Mo, and V with the highest oxidation state, and oxygen atoms. They are stoichiometrically and structurally distinct anionic molecules that exhibit diverse structures as well as manifold properties ranging from physicochemical to biological. , These structures and properties can be modified by association with cationic species such as metal complexes and free metal ions, or neutral organic compounds through electrostatic, π–π, or van der Waals interactions, respectively. − …”

A glycine ligand coordinated hybrid complex constructed from hexanuclear copper clusters and octamolybdates

“…The materials containing both the POM clusters and amino acids have promising applications in electrochemistry, biochemistry and magneto-chemistry [16,17]. However, this area has been investigated rarely [18,19]. Even though research on polyoxometalate with transition metal ions as nodes has been done extensively, little is known about heteronuclear cluster nodes.…”

“…1 [13,14,18]. The structure of the {NaCu 6 (Gly) 8 (H 2 O) 2 } 5+ cation can be described as a distorted octahedral nanocage with a Na + cation is capsulated inside.…”
