Supramolecular architecture of ((C6H5CH2)2N)(C6H4)(NH)2P(O) Fahimeh Sabbaghia* and Mehrdad Pourayoubib a) Department of Chemistry, Zanjan Branch, Islamic Azad University, Zanjan, Iran, email: fahimeh_sabbaghi@yahoo.com b) Department of Chemistry, Faculty of Science, Ferdowsi University of Mashhad, Mashhad, Iran, email: pourayoubi@um.ac.ir Phosphoric triamides are well-known for their biological activities and some other applications as extractant, solvent and ligand [1]. The crystal structure of a new diazaphosphole-holding phosphoric triamide with the formula ((C6H5CH2)2N)(C6H4)(NH)2P(O) is studied (Figure). The P—N bond made by the (C6H5CH2)2N moiety is slightly shorter than the P—N bonds of diazaphosphole ring. The benzyl moieties adopt the +ac–sc+ac+sp and +ac–sc+ac+ap conformations (ac = anticlinal, sc = synclinal, sp = synperiplanar, ap = antiperiplanar), based on the 2×C—C—C—N/C—C—N—P/C—N—P═O torsion angles. In the crystal structure, the molecules are aggregated through N—H…O═P hydrogen bonds in a tape arrangement along the a axis. This assembly includes centrosymmetric eight-membered ring hydrogen bond motifs, in which the P═O group takes part as a double-hydrogen bond acceptor. The C—H…π interactions extend the supramolecular assembly to a two-dimensional array parallel to the ab plane.
