Two Heart-Shaped Carboxylate-Substituted Selenotungstates with Photochromic Properties
Two carboxylate-substituted selenotungstates with heart-shaped structures were successfully synthesized via the reaction of Na<sub>2</sub>SeO<sub>3</sub>, Na<sub>2</sub>WO<sub>4</sub>·2H<sub>2</sub>O, dl-malic acid/glycolic acid, and dimethylamine hydrochloride in an aqueous solution. The chemical formulas of these compounds are [(CH<sub>3</sub>)<sub>2</sub>NH<sub>2</sub>]<sub>8</sub>Ba<sub>2</sub>Na<sub>2</sub>(H<sub>2</sub>O)<sub>7</sub>[Se<sub>4</sub>W<sub>31</sub>O<sub>104</sub>(OH)<sub>4</sub>(H<sub>2</sub>O)(MalH)<sub>2</sub>]·18H<sub>2</sub>O (<b>1</b>) and [(CH<sub>3</sub>)<sub>2</sub>NH<sub>2</sub>]<sub>12</sub>Ba<sub>3</sub>(H<sub>2</sub>O)<sub>8</sub>[Se<sub>4</sub>W<sub>31</sub>O<sub>108</sub>(H<sub>2</sub>O)(Gca)<sub>2</sub>]·20H<sub>2</sub>O (<b>2</b>) [Mal = malate; Gca = glycolate]. The most notable structural characteristic of these compounds is the presence of a carboxylate-substituted selenotungstate framework, a feature that is relatively uncommon among the previously reported selenotungstates. Furthermore, the experimental results demonstrate that these compounds exhibit photochromic properties.
