Slow magnetic relaxation influenced by change of symmetry from ideal C i to D 3d in cobalt(ii)-based single-ion magnets

Slow magnetic relaxation influenced by change of symmetry from ideal C i to D 3d in cobalt(ii)-based single-ion magnets

The coordination geometries of the Co(ii) site in the two complexes [Co(imidazole) ][BPh ] ·0.3CH CN (1) and [Co(imidazole) ][NO ] (2) were observed to display the ideal symmetries C and D , respectively. Both complexes were shown to be field-induced single-ion magnets. The effective energy barrier...

Zusammenfassung:The coordination geometries of the Co(ii) site in the two complexes [Co(imidazole) ][BPh ] ·0.3CH CN (1) and [Co(imidazole) ][NO ] (2) were observed to display the ideal symmetries C and D , respectively. Both complexes were shown to be field-induced single-ion magnets. The effective energy barrier was found to decrease as the local symmetry changed from low-symmetry C to high-symmetry D .
