Synthesis, characterization and structural study of new phosphoric triamides

In the present work, the synthesis and characterization of two new phosphoric triamide (PT) compounds: one iron(III)-PT complex, Fe(NO3)3[OP(NC5H10)3]2 (1) and one PT ligand, OP(NHC5H9)3 (2) are surveyed. The structure of compound 2 has been determined by X-ray crystallography. For 1, the crystallographic data were collected in temperature 100 (2) K (crystal system: monoclinic; space group: P21/c; a = 18.5257 (6) Å; b = 15.7698 (5) Å; c = 14.2471 (4) Å; β = 106.7950 (2)°; V = 3984.7 (2) Å3 and Z = 4) that confirm the formula (NO3)3Fe[OP(NC5H10)3]2 for this compound. However, these crystallographic data don’t reported here due to poor quality and high R factor. In structure of compound 2, the asymmetric unit is composed of one complete molecule. In this structure, adjacent molecules are linked via [N—H]2•••O═P hydrogen bonds in a linear arrangement along b axis in which the P═O group acts as a double hydrogen-bond acceptor.
