Magnetism gets a new twist : The crystal structure and magnetic properties of a chiral 3D ferrimagnet with T c of 35 K, [{Cr III (CN) 6 }{Mn II ( d‐ or L ‐NH 2 ala)} 3 ]⋅3 H 2 O (NH 2 ala=aminoalanine ion) are described. The complex has an extended, chiral, triple‐strand helical arrangement of Mn II ions, formed by the coordination of the organic ligands (see picture; purple Mn, gray C, blue N, red O). The triple helixes are linked to each other by the {Cr III (CN) 6 } units.
