A.C. susceptibility and iron-57 Mossbauer spectroscopy measurements ar
e used to investigate the first examples of cooperative magnetic order
ing phenomena for FeCl52- anions and the related methanol and aquo add
ucts. Depending on the counter cation and/or solvate identity examples
of uncanted antiferromagnetic and canted (weakly ferromagnetic) three
dimensional order are observed with critical temperatures -7K.
