Heterometallic Molecular and Ionic Isomers [PDF]

Numerous descriptions of structural isomerism in metal complexes do not list any molecular vs ionic isomers. At the same time, one of the most striking examples of structural isomerism in organic chemistry is molecular urea, which has the same atomic ...

Bis[μ-N-(tert-butyldimethylsilyl)quinolin-8-aminato-1:2κ2N1,N8:N8](N,N,N′,N′-tetramethylethane-1,2-diamine-1κ2N,N′)lithiumsodium

Acta Crystallographica Section E, 2012
In the heterometallic title bulky amido complex, [LiNa(C15H21N2Si)2(C6H16N2)], both alkali metal ions are four-coordinated with distorted tetrahedral geometries. The Li+ ion is N,N′-chelated by the N-silylated amido ligand, with Li—N =

Tetradecanuclear {Ni9Ln5} Clusters Featuring Encapsulated {Ln5} Trigonal Bipyramids: Modular 3d‐4f Architectures With Broad‐Range Magnetocaloric Response

Chemistry – A European Journal, Volume 32, Issue 35, 19 September 2026.
The use of 2‐aminoisobutyric acid in 3d–4f chemistry affords three {Ni₉Ln5} clusters, with the Gd analogue exhibiting an unusually broad magnetocaloric effect across an extended temperature range. ABSTRACT The solvothermal reaction between Ni(HCOO)2.2H2O, 2‐aminoisobutyric acid (aibH), Ln(OAc)3·4H2O (Ln = Gd, Y, Dy) and NEt3 in MeOH/MeCN affords the ...

Linear Pentanuclear 3d–4f M‐Gd‐M‐Gd‐M Complexes Prepared From a One‐Pot Reaction Show Intramolecular Ferromagnetic Interactions (M  =  Cu, Ni, and Co)

European Journal of Inorganic Chemistry, Volume 29, Issue 26, 16 September 2026.
Using a multidentate ligand with two distinct coordination sites and a bridging coordination site, a series of novel linear pentanuclear complexes with alternately arranged 3d and 4f ions via a one‐pot reaction were synthesized. Cryomagnetic studies revealed the presence of intramolecular ferromagnetic interactions and their magnetic entropy changes ...
