Conclusion
The study presents a new polymeric compound with a layered structure formed by barium and benzimidazole-5,6-dicarboxylate, which includes lattice water molecules interacting through hydrogen bonds.
Supporting Evidence
- The compound adopts a layer structure parallel to (001).
- Adjacent BaII atoms are connected by benzimidazole-5,6-dicarboxylate dianions.
- Lattice water molecules interact with the layers through hydrogen bonds.
Takeaway
Scientists created a new material that has layers and includes water molecules, which help hold the layers together.
Methodology
The compound was synthesized by dissolving barium chloride and 1H-benzimidazole-5,6-dicarboxylic acid in water, followed by crystal growth over several weeks.
