Synthesis, Solid‐State Structure, and Bonding Analysis of a Homoleptic Beryllium Azide

Abstract

Beryllium azides tend to form predominantly ionic bonds, but are also expected to show covalent bonding contributions owing to the small size of the Be 2+ ion and its high charge density.However,even though Be(N 3 ) 2[1] and solvent-coordinated beryllium azide complexes L 2 Be(N 3 ) 2 (L = THF,p yridine) [2] 6 ]( X = Cl, Br) differ significantly as is typical for covalently bonded azides (type B in Scheme 1), [3] while those of the terminal azides are almost identical, indicating ah igh degree of ionic bonding (type C).

Recent Contributions to the Coordination Chemistry of Beryllium

“…Quantum‐chemical studies showed that the energy difference between the different azidoberyllate species is very small. This is the reason for the establishment of the observed equilibria and is in line with the behavior of the chloroberyllates …”

“…This is the reason fort he establishmento ft he observed equilibria and is in line with the behavior of the chloroberyllates. [115] The reactivity of the beryllates has been scarcely investigated and to the best of the author'sk nowledge only the in Scheme18d epictedconversions-all startingfrom hexachlorodiberyllate-are known. Beryllate 128 reacts with hexamethyltrisiloxane to tetramethylsiloxanato-bridged tetranuclear anion 141.T he same reaction presumably also occurs when silicon grease is exposed to beryllate 128.…”

Speculative assessment, molecular composition, PDOS, topology exploration (ELF, LOL, RDG), ligand-protein interactions, on 5-bromo-3-nitropyridine-2-carbonitrile

“…For the synthesis of insecticides, herbicides, medicinal products, supplements, food flavourings, food additives, synthetic compounds, detonators, antimicrobials, and sealants, the pyridine and its components are reused as solvents and as the starting material [14,15,16]. Real and synthetic compounds with the cyanopyridine moiety have also validated imperative antibacterial and antifungal activities in assessment to biologically active compounds with a carbon-nitrogen bond [17,18,19,20]. The review of literature connotes that the no DFT studies have been done on the 5-Bromo-3-nitropyridine-2-carbonitrile thus far.…”

The Phosphonium Ion [Cy3PCHCl2]+: Synthesis and Properties

“…Tetraphenyl phosphonium ( 1 ) (Figure ) is widely employed as a weakly coordinating cation . Even though the weak interaction between the phosphonium ion and the investigated anion is generally desirable this has the drawback, that the anions are frequently disordered in the crystal lattice .…”
