Balancing the critical property requirements is key to surmounting the obstacles in the application of nonlinear optical (NLO) crystals. Tricoordinated units, characterized by nearly the lowest coordination number, are common in inorganic NLO-active oxides; however, crystals solely composed of such units are rare. Herein, by assembling three distinct tricoordinated units (SbO, TeO, and NO) into a single crystal, a pioneering fully tricoordinated NLO material, (SbTeO)(NO), was synthesized a facile volatilization method.

Article Synopsis
- Vinylidene rearrangement of alkynes is a powerful method for transforming alkynes, but the application of borylalkynes in this process has not been extensively studied.
- This research explores the rearrangement of internal borylalkynes using a cationic ruthenium complex, highlighting that the reaction is effective for both tri- and tetracoordinate boryl groups, with reaction rates significantly influenced by the Lewis acidity of the boryl group.
- The study found that the rearrangement involves 1,2-boryl migration and showed that tricoordinate boryl groups migrate via an electrophilic process, contrasting with previous methods involving vinylidene rearrangements of internal alkyn

L-Glutamic acid (Glu) plays a pivotal role in amino acid metabolism in living organisms. Theoretical knowledge of how metabolism propagates the nitrogen isotope composition (δN) is essential for elucidating the mechanism of amino acid metabolism . In this paper, to estimate the nitrogen isotope fractionation involving Glu and its protonated/deprotonated species, their nitrogen isotopic reduction partition function ratios (RPFRs) were calculated at the apfd/6-311+G(2d,p) level of theory by the SCRF method.

The formation of isomers when trapping floppy cluster ions in a temperature-controlled ion trap is a generally observed phenomenon. This involves collisional quenching of the ions initially formed at high temperature by buffer gas cooling until their internal energies fall below the barriers in the potential energy surface that separate them. Here we explore the kinetics at play in the case of the two isomers adopted by the H(HO) cluster ion that differ in the proton accommodation motif.

The reactions leading to the formation of C-heteroatom bonds in the coordination sphere of Au(III) complexes are uncommon, and their mechanisms are not well known. This work reports on the synthesis and reductive elimination reactions of a series of Au(III) methyl complexes containing different Au-heteroatom bonds. Complexes [Au(CF)(Me)(X)(PR)] (R = Ph, X = OTf, OClO, ONO, OC(O)CF, F, Cl, Br; R = Cy, X = Me, OTf, Br) were obtained by the reaction of -[Au(CF)(Me)(PR)] (R = Ph, Cy) with HX.
