| description | Polymeric terbium(III) squarate hydrate [{Tb<sub>2</sub>(C<sub>4</sub>O<sub>4</sub>)<sub>3</sub>(H<sub>2</sub>O)<sub>8</sub>}<sub>n</sub>] was prepared from TbCl<sub>3</sub> or Tb<sub>2</sub>O<sub>3</sub> and squaric acid. The crystal structure was determined in a monoclinic <i>Pc</i> space group, and the whole molecular arrangement gives a sandwiched two-dimensional structure. The coordination polyhedra are described as a square antiprism. The solid complex emits green light under UV irradiation at room temperature with the quantum yield of 25%. Although Tb<sup>3+</sup> is a non-Kramers ion, the alternating-current magnetic susceptibility showed frequency dependence in a 2000-Oe DC field, and the effective energy barrier for magnetization reorientation was 33(2) K. Thus, [{Tb<sub>2</sub>(C<sub>4</sub>O<sub>4</sub>)<sub>3</sub>(H<sub>2</sub>O)<sub>8</sub>}<sub>n</sub>] displayed functions of a potential luminescent magnet. |
