“…Polynuclear iron coordination clusters have received considerable attention since the discovery that they can serve as models for protein active sites [ 1 ] and exhibit interesting magnetic properties including slow magnetization relaxation and quantum tunneling phenomena [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ]. Tremendous efforts have been devoted to the development of new synthetic routes to increase the nuclearity of such clusters.…”
