Abstract

Abstract : The first example of a Ni II –Cr III chain to exhibit slow relaxation of magnetization is reported. Abstract : The reaction of [Cr3 III O(OAc)6 (H2 O)3 ]NO3 ·AcOH with 2-hydroxynaphthaldehyde, 2-amino-isobutyric acid and NiCl2 ·6H2 O in MeOH, under basic and solvothermal conditions, led to the formation of the quasi-1D coordination polymer {[Cr III 2 Ni 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.
