摘要
A combination of a.c. susceptometry and Fe-57 Mossbauer spectroscopy measurements confirm valence trapped 3D-ferrimagnetically ordered ground states for the title compounds save (A) that orders antiferromagnetically with a very broad maximum in chi'(m) centered at similar to 50K. Their ground state magnetic behavior is contrasted with the previously demonstrated ferromagnetism of Bu(4)N{(FeCrIII)-Cr-II(ox(3))} and phi(4)P{(MnCrIII)-Cr-II(ox(3))}.
