Cryst Growth Des . 2024 Nov; 24(21):9076-9083. PMID: 39534426
The initial use of 2-(pyridin-2-yl)propane-1,3-diol (pypdH) in Mn cluster chemistry has afforded two new mixed-valence polynuclear Mn clusters, namely, [MnΟ(pypd)(hmp)(OCCMe)] () and [MnΟ(N)(pypd){(py)CO}(OCEt)] () (hmp = deprotonated 2-hydroxymethylpyridine; (py)CO =...

Brown S, Marchi S, Thomas C, Hale A, Lockart M, Bowman M, et al.
J Inorg Biochem . 2023 Dec; 251:112439. PMID: 38039560
The reduction of the carcinogen chromate has been proposed to lead to three Cr(III)-containing DNA lesions: binary adducts (Cr(III) and DNA), interstrand crosslinks, and ternary adducts (Cr(III) linking DNA to...

Lee K, Christou G
Inorg Chem . 2023 Nov; 62(49):20005-20019. PMID: 37922406
The previous development of a magnetostructural correlation (MSC) for polynuclear Fe/oxo clusters has now been extended to one for polynuclear Mn/oxo clusters. A semiempirical model estimating each pairwise Mn exchange...

Acosta C, Belov D, Lamur A, Brantley C, Solans-Monfort X, Rue K, et al.
Inorg Chem . 2023 Oct; 62(44):18108-18115. PMID: 37876243
The reaction between silylamido complexes of Cr(II), Fe(II), and Co(II) and IMes·2HF salt in the presence of IMes (IMes = 1,3-dimesitylimidazol-2-ylidene) led to isolation of Cr(IMes)F (), Fe(IMes)F (), and...

Yazback M, Liu S, Shatruk M, Christou G, Cheng H
J Phys Chem A . 2023 Apr; 127(17):3814-3823. PMID: 37093629
Using first-principles methods and spin models, we investigate the magnetic properties of transition-metal trimers Cr and Cu. We calculate exchange coupling constants and zero-field splitting parameters using density functional theory...

Hale A, Abboud K, Christou G
Inorg Chem . 2023 Apr; 62(15):6020-6031. PMID: 37015039
New members of the Mn and Mn torus-like cluster family have been prepared from a hybrid comproportionation-alcoholysis reaction of [MnO(OCR)(HO)] in alcohol in the presence of R'COH with NBuMnO or...

Dalton Trans . 2022 Nov; 51(47):18077-18089. PMID: 36373936
The systematic investigation of the general reaction scheme Dy/X/LH, where X = Cl, CFSO, ClO, MeCO, and LH is the pocket-type ligand 2,6-diacetylpyridine bis(picolinoylhydrazone), resulting from the condensation of 2,6-diacetylpyridine...

Inorg Chem . 2022 Oct; 61(43):17256-17267. PMID: 36251497
The synthesis and characterization of a high-nuclearity Fe/O/arsinate cluster is reported within the salt [FeO(OH)(OAsMe)(OCH)(HO)](NO) (). The compound was prepared from the reaction of Fe(NO)·9HO, dimethylarsinic acid (MeAsOH), and triethylamine...

Aebersold L, Hale A, Christou G, Peralta J
J Phys Chem A . 2022 Sep; 126(38):6790-6800. PMID: 36129336
In this work, we assess the potential of the Green's function approximation to predict isotropic magnetic exchange couplings and to reproduce the standard broken-symmetry energy difference approach for transition metal...

J Phys Chem A . 2022 Aug; 126(32):5265-5272. PMID: 35939333
We study intramolecular electron transfer in the single-molecule magnetic complex [MnO(OCR) (HO)] for R = -H, -CH, -CHCl, -CH, and -CHF ligands as a mechanism for switching of the molecular...
