Slow magnetic relaxations in azide or formate bridged chains based on dicubane-like 3d-4f clusters

Dicubane-like 3d-4f subunits are linked by azide or formate giving a series of 1D chains. The linkers of azide or formate have little influence on the structure of the M2Ln2 subunits. Magnetic study indicated that ferromagnetic interactions exist in the chains of those complexes. At low temperature...

Description
Summary:Dicubane-like 3d-4f subunits are linked by azide or formate giving a series of 1D chains. The linkers of azide or formate have little influence on the structure of the M2Ln2 subunits. Magnetic study indicated that ferromagnetic interactions exist in the chains of those complexes. At low temperature all the involved cobalt complexes exhibit slow magnetic relaxation.
