In this study, one new phosphoric triamide with the chemical formula (Cl3CC(O)NH)P(O)(NHCH(CH3)2)2 was synthesized and characterized using melting point analysis, infrared (IR) and nuclear magnetic resonance (NMR) spectroscopies and X-ray crystallography method. Crystallographic data were collected at 120 K, and the compound exhibits a monoclinic crystal system with the space group P21/c. The unit cell parameters are a = 9.9287 (1) (Å), b = 16.2853 (2) (Å), c = 9.6290 (1) (Å), β (°) = 102.767 (1), V (Å3) = 1518.44 (3) and Z = 4. In the crystal structure, the molecules are connected through NH…O=P hydrogen bonds, in a tape arrangement. These hydrogen bonds appear large red areas on the Hirshfeld surface map. The fingerprint plot shows the most significant contributions of H…H (40.7%) and H…Cl/Cl…H (37.9%) in the crystal.
