Interplay of structural and magnetic properties in copper(II) sulfate hydrates CuSO4×nH2O — Maria Rosner1,2, Anne Henschel1, Yurii Prots1, Marcus Schmidt1, •Helge Rosner1, and Andreas Leithe-Jasper1 — 1MPI CPfS Dresden, Germany — 2Martin-Andersen-Nexö-Gymnasium Dresden
Copper(II)-sulfate pentahydrate CuSO4×5H2O is likely the most abundant Cu(II) compound and well studied, including its quasi one-dimensional spin 1/2 magnetism. However, copper(II)-sulfates exist as a series of compounds CuSO4×nH2O (n=0,1,3,5) that differ in their degree of hydration, exhibiting very distinct crystal structures and, in consequence, pronounced differences in their properties. Here, we present a systematic investigation of the series, comprising synthesis (powder and single crystals) , structural (XRD) and thermodynamical (DTA/TG, Cp, χ) characterization as well as electronic structure calculations. As the result, we obtain a consistent picture of the development of the magnetic behavior upon dehydration.
