Data for Heterometallic trinuclear {CoIIILnIII} (Ln = Gd, Tb, Ho and Er) complexes in a bent geometry. Field-induced single-ion magnetic behavior of the ErIII and TbIII analogues Joydeb Goura (1576225) Jamie Brambleby (1422472) Craig V.

The metallic core of these complexes consists of a (CoIII–LnIII–CoIII) motif bridged in a bent geometry resulting in six-coordinated distorted CoIII octahedra and nine-coordinated LnIII monocapped square-antiprisms. The magnetic characterization of these compounds reveals the erbium and terbium analogues to display a field induced single-ion magnetic behavior similar to the dysprosium analogue but at lower temperatures. The energy barrier for the reversal of the magnetization of the CoIII2TbIII analogue is Ueff ≥ 15.6(4) K, while for the CoIII2ErIII analogue Ueff ≥ 9.9(8) K. The magnetic properties are discussed in terms of distortions of the 4f electron cloud.<br><br>Fig6a, Fig6b, Fig7ab, Fig7cd, Fig8ab, Fig8cd, Fig9, Fig10, Fig11a, Fig11b, Fig11c, Fig12ab, Fig12cd, Fig13, Fig14ab, Fig14cd 2026-09-14T07:48:31Z Dataset Dataset 10.82444/warw.33720412.v1 https://figshare.com/articles/dataset/Data_for_Heterometallic_trinuclear_CoIIILnIII_Ln_Gd_Tb_Ho_and_Er_complexes_in_a_bent_geometry_Field-induced_single-ion_magnetic_behavior_of_the_ErIII_and_TbIII_analogues/33720412 CC BY 4.0
