| Popis: | Colourless crystal of the title compound, K+·C10H5O8−·3H2O, were isolated under hydrothermal conditions (423 K, 72 h). The structure consists of trihydrogen 1,2,4,5-benzenetetracarboxylate (H3btec−) anions, potassium cations and water of crystallization. Each K+ cation is seven-coordinated by four carboxylate O atoms and three water O atoms. In turn, each H3btec− anion connects to four K+ cations and so an undulating layer forms. Adjacent layers are held together by hydrogen bonds to form a three-dimensional network. A short intramolecular hydrogen bond is found to exist in the H3btec− anions. |
