✦ Synopsis

Chiral triple-helical strands are found in the crystal structures of the compounds [{Cr III (CN) 6 }(Mn II L) 3 ]•3 H 2 O (where L is either l-NH 2 ala or l-NH 2 ala; NH 2 alaH = aminoalanine). All the spins on the manganese ions within this arrangement display a ferrimagnetic order below 35 K as a result of linking through the cyanide bridges formed with the [Cr III (CN) 6 ] 3À ions, and indicated by the red arrow in the picture.
