| description | Novel synthesis of 2,5-bis[(1,3-thiazol-2-ylmethyl)amino]methyl-1,3,4-oxadiazole (LThiazole) is reported, along with the preparation of three new dinuclear Fe(II) complexes with different counterions [Fe<sup>II</sup><sub>2</sub>(μ<sub>2</sub>-<b>L<sup>Thiazole</sup></b>)<sub>2</sub>](BF<sub>4</sub>)<sub>4</sub>·2CH<sub>3</sub>CN (<b>1</b>), [Fe<sup>II</sup><sub>2</sub>(μ<sub>2</sub>-<b>L<sup>Thiazole</sup></b>)<sub>2</sub>](ClO<sub>4</sub>)<sub>4</sub> (<b>2</b>) and [Fe<sup>II</sup><sub>2</sub>(μ2-<b>L<sup>Thiazole</sup></b>)<sub>2</sub>](CF<sub>3</sub>SO<sub>3</sub>)<sub>4</sub>·2CH<sub>3</sub>CN (<b>3</b>).

The structure of the crystalline material was determined at 120 K for <b>1</b> and <b>3</b>. The magnetic properties of all three complexes (<b>1</b>–<b>3</b>) were measured between 2–300 K and clearly show that all three complexes stay in the high-spin state over the measured temperature range. |
