Abstract

The reaction of [Cr₃^IIIO(OAc)₆(H₂O)₃]NO₃·AcOH with 2-hydroxynaphthaldehyde, 2-amino-isobutyric acid and NiCl₂·6H₂O in MeOH, under basic and solvothermal conditions, led to the formation of the quasi-1D coordination polymer {[Cr^III₂Ni^II(L)₄(MeOH)₂]}_n (where L = the dianion of the Schiff base between 2-hydroxynaphthaldehyde and 2-amino-isobutyric acid), which behaves as a ferromagnetic chain, displaying slow relaxation of magnetization.
