• Magnetic Behavior Control in Niccolite Structural Metal ...

    By changing template cation but introducing trivalent iron ions in the known niccolite structural metal formate frameworks, three complexes formulated [NH2(CH3)2][FeIIIMII(HCOO)6] (M = Fe for 1, Mn for 2, and Co for 3) were synthesized and magnetically characterized. The variation in the compositions of the complexes leads to three different complexes: mixedvalent complex 1, heterometallic ...
