Abstract:
The insertion of “sandwiched spins” between magnetic layers could efficiently affect the interlayer magnetic correlations, but doing so increases the complexity in the interlayer spin alignment because of competition between the inserted spin‐layer interaction J NNI and the interlayer through‐space interaction J NNNI if the magnitude of J NNI is of the same order as J NNNI with reciprocal signs of the respective interactions. Herein, systematic tuning of the magnetic phase variations by J NNI and J NNNI in two kinds of metal‐variable isostructural series of supramolecular pillared layer magnets [MCp* 2 ][{Ru 2 II,II (2,3,5,6‐F 4 CO 2 ) 4 } 2 (TCNQ)] ⋅ 2 DCE (M=Co, Fe, Cr; 2,3,5,6‐F 4 PhCO 2 − =2,3,5,6‐tetrafluorobenzoate; TCNQ=7,7,8,8‐tetracyano‐ p ‐quinodimethane; DCE=1,2‐dichloroethane) and their DCE‐free series, in which [MCp* 2 ] + (Cp*=η 5 ‐C 5 Me 5 ) species with S= 0, 1/2, and 3/2 for M=Co, Fe, Cr, respectively, are sandwiched between ferrimagnetic layers of [{Ru 2 } 2 (TCNQ)] − , is demonstrated. The results showed that the flexible magnetic natures of these magnets are changeable in dependence on J NNI and J NNNI , as well as on interlayer inserted spins M.
