Copper(II) halides continued to provide examples of interesting low dimensional systems. In the cases discussed, inequivalent Cu-X-Cu linkages are the basis for the novel magnetic behavior. (N-methylphenethylammonium)CuCl3provides an example of chains with alternating FM interactions. The compound (C6N2H8)2Cu3Br8contains chains of Cu3Br82-trimers. Strong AFM coupling in the trimers lead to S=1/2 ground states, which are then coupled together to form FM chains. Cu(cyclam)CuCl4contains chains with alternating FM/AFM interactions, where JFM≫|JAFM| so they should behave as S=l Haldane chains at low T. The compound (Et3MeN)3Cu4Cl11contains FM tetrametric units linked into chains by weak AFM coupling, defining a potential S=2 Haldane chain at low T.
