abstract = {The reaction of Schiff base ligand N,N0-bis(salicylidene)ethylenediamine (H2L) with [CoII
2(m-
OH2)(O2CCMe3)4(HO2CCMe3)4] (CoII
2-Piv) (Piv = pivalate) and Ln(NO3)3 xH2O (for 1, 3, 4 x = 5; for 2, x = 6)
salts in the presence of triethylamine afforded [CoIIILnIII(L)(m-Piv)2(Z1-Piv)2(Z1-OHMe)2] [where Ln = Dy, for 1;
Tb, for 2; Ho, for 3; and Er, for 4] complexes. The heterometallic dinuclear ensemble is built via the bridging
coordination action of [L]2  and four [Piv]  ligands. Further, the Ln(III) center is coordinated by two Z1-OHMe
ligands. Shape analysis of all the Ln(III) centers in 1–4 reveals the existence of a distorted triangular dodecahedron
geometry. Magnetic studies revealed that compound 1 shows slow magnetic relaxation under zerofield
at low temperatures whereas compound 4 displays field-induced slow magnetic relaxation. This
phenomenon is in agreement with the results of theoretical studies.},
