Title: Direct observation of the role of lanthanides in stabilizing a ferromagnetic spin orientation in a weak Fe(III)-Fe(III) antiferromagnet Author:Xiang, Hua; Mereacre, Valeriu; Lan, Yanhua; Lu, Tong-Bu; Anson, Christopher E; Powell, Annie K Subject:Magnetic Fields ; Orientation ; Antiferromagnetism ; Modulation ; Ferromagnetism ; Dysprosium ; Spectra ; Iron ; Miscellaneous Sciences (So) ; Components and Materials (General) (Ea); Description:
[Fe(III)2Ln(III)2(OH)2(L(1))2(HL(2))2(NO3)4(H2O)1½(MeOH)½]·6MeCN (Ln = Y (1), Dy (2); H2L(1) = 2,3-dihydroxybenzaldehyde and H2L(2) is the Schiff base of this aldehyde with furfurylamine) have unusually weak antiferromagnetic interactions between the Fe(III) centres in comparison with other (μ-dihydroxo)diiron(III) complexes. For 1, it was established that modulation of the hydroxo bridges by coordination to the Y(III) ions results in long Fe-O bonds and small Fe-O-Fe angles, leading to J = -0.4 cm(-1). Analysis of the Mössbauer spectra reveals that the intramolecular magnetic field generated by the anisotropic Dy(III) ions in 2 is sufficient to overcome the Fe-Fe antiferromagnetic coupling and reorientate the Fe(III) moments into a ferromagnetic spin orientation.

Title: Magnetic anisotropy of a Co single ion magnet with distorted trigonal prismatic coordination: theory and experiment Author:Peng, Yan; Bodenstein, Tilmann; Fink, Karin; Mereacre, Valeriu; Anson, Christopher E; Powell, Annie K Subject:Chemistry; Description:
The single ion magnetic properties of Co(ii) are affected by the details of the coordination geometry of the ion. Here we show that a geometry close to trigonal prismatic which arises when the ligand 6,6'-((1Z)-((piperazine-1,4-diylbis(propane-3,1-diyl))bis(azanylylidene))bis(methanylylidene))bis(2-methoxyphenol) coordinates to Co(ii) does indeed lead to enhanced single-ion behaviour as has previously been predicted. Synthesis of the compound, structural information, and static as well as dynamic magnetic data are presented along with an analysis using quantum chemical ab initio calculations. Though the complex shows a slight deviation from an ideal trigonal prismatic coordination, the zero-field splitting as well as the g-tensor are strongly axial with D = -41 cm and E < 0.01 cm. For the lowest Kramers doublet (S = 1/2) g = 7.86 and g < 0.05 were found. In contrast, the second Kramers doublet possesses a rhombic g-tensor with g = 2.75 and g = 4.35. Due to large spin-orbit coupling resulting...
