We report on the magnetic properties of the complex bimetallic compound [Cr(H2O)(NH3)5][FeCl6] studied by ac magnetic susceptibility and magnetization techniques in the range 1.5-30 K and 0-40 kOe. The crystal structure contains discrete [Cr(H2O)(NH3)5]3+ and [FeCl6]3- ions, held together by ionic forces and by a network of hydrogen bonds. At temperatures below (2.32±0.01) K the compound seems to behave as a noncollinear ferrimagnet. In addition, the experimental H-T magnetic phase diagram has been derived. © 1992.
