Abstract

Two new complexes, [Fe33-O)(inicH)6(H2O)3][Gd(NO3)6]·(NO3)4·nH2O(1) and [Fe33-O)(inicH)6(H2O)3][Dy(NO3)5 (H2O)]·(NO3)5·n(H2O)(2) with two isolated complex moieties, were generated when isonicotinicacid was treated with iron(III) nitrate and the corresponding lanthanide(III)nitrate in water. The structures were determined by single-crystal X-raydiffraction studies. In these compounds, the anionic lanthanide complexes areencapsulated by trinuclear [Fe33-O)(inicH)6(H2O)3]7+ cationiccluster units, which is facilitated by hydrogen-bonding interactions.Investigation of the magnetic properties reveals that 2 showsslow relaxation of magnetization at low magnetic field (Hdc =1.0 kOe), with an energy barrier of 23 K originating from a single [Dy(NO3)5(H2O)]2– anion.
