| Abstract: | Calcium biuretooxophosphate CaPO2(NH)3(CO)2]2 was synthesized by ion exchange reaction in aqueous solution. The crystal structure of the salt was elucidated by single‐crystal X‐ray diffraction. Anionic 1‐phospha‐2, 4, 6‐s‐triazine rings exhibiting a half‐chair conformation act as monodentate ligands for the calcium ions. A 3D network is formed by the resulting CaO6 octahedrons together with the anionic rings interconnected by hydrogen bonds. Beside the crystal structure, FTIR and photoluminescence spectra of calcium biuretooxophosphate are discussed. The thermal behavior of the salt is examined by means of temperature‐dependent powder X‐ray diffraction measurements and combined TG and DTA analyses. |
