The judicious selection and combination of multicomponents provide great potential for the further exploration of new polyoxometalate (POM) materials. Here, a delicate control on tungstate, Sb and Bi sources, Eu ions, and organic molecules led to the discovery of a novel multimetal cluster-embedded POM [HN(CH)]NaH{[Eu(HO)SbBiWO](SbWO)(SbWO)}·78HO (). The polyoxoanion of was constructed from four in situ-formed [SbWO] and [SbWO] building blocks connected by two hexa-metallic [Eu(HO)SbBiWO] clusters, to be a rare member of Sb- and Bi-coexisting POM.

The 5,6-Bis(diisopropylphosphino)acenaphthene -stabilized Sb(I) cationic compound [LSb][OTf] (OTf = CFSO) possessing two lone pairs of electrons on the Sb(I) center showed nucleophilic behavior toward methyl trifluoromethanesulfonate forming the oxidized product [LSbMe][OTf] (OTf = CFSO). Reaction of compound with Lewis acids such as GaCl and AlBr led to changes in the counteranions only giving products [LSb][GaCl] and [LSb][SbBr] , respectively. A metathesis reaction was observed when compound was reacted with PI.

Structurally constrained, cationic P compound [LP][SbCl] with an OCO pincer-type ligand (L) having a central carbene donor was directly synthesized via an Sb-to-P metathesis reaction between PCl and LSb-Cl. [LP][SbCl] was isolated and its reactivity with small molecules (ROH and RNH) was studied, showing that [SbCl] is not an innocent counter anion, but an active participant in these reactions. When the [SbCl] was replaced with the [CBH] ([Cb]) anion, the reactions were redirected to [LP] cation only.

Exploring a zero-dimensional (0D) hybrid halide with a large Stokes shift and efficient broad-band emission is highly desirable due to its enormous potential for solid-state lighting (SSL) application. However, it is still challenging to develop a highly emissive 0D hybrid halide with low toxicity and remarkable stability. Herein, we developed a novel indium-based metal halide AInCl·4HO (A = doubly protonated 1,4-diaminobutane) whose inorganic octahedrons are completely isolated by the organic cations to form the 0D structure.

Article Synopsis
- * The study investigated pioneer phytoremediation's effects on the migration and transformation of PTEs, specifically focusing on thallium (Tl), mercury (Hg), arsenic (As), and antimony (Sb) in mercury-thallium mine waste.
- * Findings revealed that while pioneer plants enhanced the mobility of certain elements like Hg and As through organic compounds, they also reduced Tl migration by changing the chemistry of the waste, which increased its ability to adsorb metal cations but hindered the adsorption of negatively charged anions like As
