Reaction of 2 equiv. of the lithium carboranylamidinate Li[-(CHB)C(NCy)(NHCy)] with SnCl in THF afforded the stannylene compound bis(,'-dicyclohexylamidinatocarboranate)tin(II), Sn[-(CHB)C(NCy)(NHCy)] (). A similar reaction of SnCl with 2 equiv. of Li[-(CHB)C(N Pr)(NH Pr)] unexpectedly afforded the known solvated penta-chlorido-stannate(IV) salt [Li(THF)][SnCl(THF)] as the main reaction product. Small amounts of the new chlorido-tin(IV) bis-(carboranylamidinate) bis(,'-diiso-propylamidinatocarboranate)chloridotin(IV), SnCl[-(CHB)C(N Pr)(NH Pr)][-(CHB)C(N Pr)] (), were isolated as a by-product. Single-crystal X-ray structure analysis revealed a ,-chelating coordination of the carboranylamidinate ligands in both and . The Sn atom in adopts a pseudo-trigonal-bipyramidal coordination under participation of a stereoactive lone pair. In , a trigonal-bipyramidal coordination of Sn is completed by a chlorido ligand.

In the past decade, significant efforts have been made to develop efficient half-Heusler (HH) based thermoelectric (TE) materials. However, their practical applications remain limited due to various challenges occurring during the fabrication of TE devices, particularly the development of stable contacts with low interfacial resistance. In this study, we have made an effort to explore a stable contact material with low interfacial resistance for an n-type TiCoSb-based TE material, specifically TiNbCoSbBi as a proof of concept, using a straightforward facile synthesis route of spark plasma sintering.

Van der Waals (vdWs) materials are promising candidates for hetero-integration with silicon photonics toward miniaturization and integration. VdWs materials like molybdenum telluride and black phosphorus, despite being prominent, exhibit air sensitivity, and their room temperature emissions can be significantly broadened by tens of meV. Here, a self-encapsulation strategy is developed to scalably synthesize robust 2D vdWs ErOCl with sub-meV narrow emissions at the telecom C-band.

A concise and convergent synthesis of the isosteroidal alkaloids veratramine and 20--veratramine has been accomplished. A Horner-Wadsworth-Emmons olefination joins two chiral building blocks of approximately equal complexity and a transition-metal catalyzed intramolecular Diels-Alder cycloaddition-aromatization cascade constructs the tetrasubstituted arene. Other key steps include a highly diastereoselective crotylation of an -sulfonyl iminium ion and an Eschenmoser fragmentation.

This work reports the synthesis of a copper metal complex with the nonsteroidal anti-inflammatory drug (NSAID) ibuprofen, and 2,2'-dipyridylamine employing microwave-assisted synthesis (MWAS). To the best of authors knowledge, this is the first study reporting a NSAID-based complex achieved through MWAS. The coordination compound was characterised by elemental analysis, Fourier transform infrared spectroscopy, thermogravimetry, and ultraviolet-visible spectrophotometry.
