Abstract

original image

Magnetismus mit neuem Dreh: Der chirale 3D-Ferrimagnet [{CrIII(CN)6}{MnII(d- oder L-NH2ala)}3]⋅3 H2O (NH2ala=Aminoalanin-Ion) mit Tc=35 K ist durch eine ausgedehnte, chirale, tripelhelicale Anordnung von MnII-Ionen gekennzeichnet, die durch die Koordination der organischen Liganden verursacht wird (siehe Bild; violett Mn, grau C, blau N, rot O). Die Tripelhelices sind durch die {CrIII(CN)6}-Einheiten verbunden.
