Ferro/antiferromagnetism mediated by interlayer organic spacers in layered copper(II) compounds
Abstract
Spectacular and unexpected behaviours from long-range antiferromagnetic to ferromagnetic states are observed for a novel family of layered compounds, Cu2(OH)3X·mH2O (X =n-alkylcarboxylate) depending on the layer spacing (up to ca. 28 Å); in contrast, the analogous n-alkylsulfate derivatives are predominantly three-dimensional antiferromagnets.
