The alkaline earth elements (Be, Mg, Ca, Sr, Ba) strongly favor the formation of diamagnetic com-pounds in the +2 oxidation state. Herein, we report a paramagnetic beryllium radical cation, [(CAAC)2Be]+● [CAAC = cyclic (al-kyl)(amino)carbene] (2), prepared by oxidation of a zero-valent beryllium complex with TEMPO (2, 2, 6, 6-tetramethylpiperidine-1-oxyl). Compound 2 was characterized by EPR spectroscopy, elemental anal-ysis, X-ray crystallography, and DFT calculations. Notably, compound 2…

A Neutral Beryllium(I) Radical
Abstract The reduction of a cyclic alkyl(amino)carbene (CAAC)‐stabilized organoberyllium chloride yields the first neutral beryllium radical, which was characterized by EPR, IR, and UV/Vis
Behavior of beryllium halides and triflate in acetonitrile solutions
Abstract The solution behavior of beryllium halides and triflate in acetonitrile was studied by NMR, IR and Raman spectroscopy. Thereby mononuclear units [(MeCN)2BeX2] (X = Cl, Br, I, OTf) were
π Back-Donation from a Beryllium Dibromide Fragment at the Expense of Its σ Strength.
TLDR
Light is shed on the unusually high Be-C bond strength in carbene adducts to beryllium compounds and the results of energy decomposition analysis in combination with natural orbital for chemical valence and quantum theory of atoms-in-molecules analysis are obtained.
Di(indenyl)beryllium.
TLDR
The bonding in beryllocene, [BeCp 2 ], took decades to establish, owing to its unexpected mixed hapticity structure, but mechanochemical preparation, involving the solvent-free grinding of BeBr 2 and potassium indenides, leads to the production of discrete (indenyl)beryllium complexes.
Versatile Coordination Modes of Multidentate Neutral Amine Ligands with Group 1 Metal Cations
This work comprehensively investigated the coordination chemistry of a hexa-dentate neutral amine ligand, namely, N,N′,N”-tris-(2-N-diethylaminoethyl)-1,4,7-triaza-cyclononane (DETAN), with group-1
d–d Dative Bonding Between Iron and the Alkaline‐Earth Metals Calcium, Strontium, and Barium
TLDR
A comprehensive bonding analysis of all 1‐Ae complexes shows that the heavier species 1‐Ca, 1‐Sr, and 1‐Ba possess genuine Fe→Ae bonds which involve vacant d‐orbitals of the alkaline‐earth atoms and partially filled d‐ orbitals on Fe.
New horizons in low oxidation state group 2 metal chemistry.
TLDR
The most recent developments in low-valent group 2 metal chemistry will revive this area and undoubtly lead to new reactivities and applications.
Tris(carbene) Stabilization of Monomeric Magnesium Cations: A Neutral, Nontethered Ligand Approach
TLDR
The syntheses and structural characterization of bis(carbene)- and tris( carbene)-stabilized organomagnesium cations are described and the reaction of the N-heterocyclic carbene (NHC) stabilized is described.
Intriguing structural, bonding and reactivity features in some beryllium containing complexes.
TLDR
The contribution to beryllium chemistry is highlighted, including the smallest 2π aromatic system, Be32-, which also exhibits rare bond-stretch isomerism and the complex comprising an unusual Be(i) oxidation state, [BeI(cAACAr)2]+˙ and di-ortho-beryllated carbodiphosphorane exhibiting Be⇇C double dative bonds.
Ethylenediamine complexes of the beryllium halides and pseudo-halides.
TLDR
The anions were found to have a distinct influence on the solubility as well as on the species present in solution and the solid state, while ethylenediamine can act as mono- and bidentate ligand or as a crystal solvent.
