| description | A series of heterometallic carboxylate 1D polymers of the general formula [Ln<sup>III</sup>Cd<sub>2</sub>(piv)<sub>7</sub>(H<sub>2</sub>O)<sub>2</sub>]<sub>n</sub>·nMeCN (Ln<sup>III</sup> = Sm (<b>1</b>), Eu (<b>2</b>), Tb (<b>3</b>), Dy (<b>4</b>), Ho (<b>5</b>), Er (<b>6</b>), Yb (<b>7</b>); piv = anion of trimethylacetic acid) was synthesized and structurally characterized. The use of Cd<sup>II</sup> instead of Zn<sup>II</sup> under similar synthetic conditions resulted in the formation of 1D polymers, in contrast to molecular trinuclear complexes with Ln<sup>III</sup>Zn<sub>2</sub> cores. All complexes <b>1</b>–<b>7</b> are isostructural. The luminescent emission and excitation spectra for <b>2</b>–<b>4</b> have been studied, the luminescence decay kinetics for <b>2</b> and <b>3</b> was measured. Magnetic properties of the complexes <b>3</b>–<b>5</b> and <b>7</b> have been studied; <b>4</b> and <b>7</b> exhibited the properties of field-induced single-molecule magnets in an applied external magnetic field. Magnetic properties of <b>4</b> and <b>7</b> were modelled using results of SA-CASSCF/SO-RASSI calculations and SINGLE_ANISO procedure. Based on the analysis of the magnetization relaxation and the results of <i>ab initio</i> calculations, it was found that relaxation in <b>4</b> predominantly occurred by the sum of the Raman and QTM mechanisms, and by the sum of the direct and Raman mechanisms in the case of <b>7</b>. |
