    2-(4-Methylpyridin-2-yl)-4?,4?,6?,6?- tetrakis(pyrrolidin-1-yl)-1H,2H-spiro[naphtho[1,2-e][1,3,2]oxazaphosphinine-3, 2?-[1,3,5,2,4,6]triazatriphosphinine]

    In the title spiro-phosphazene derivative, C33H 46N9OP3, the phosphazene and six-membered N/O rings are in flattened chair and twisted-boat conformations, respectively. The naphthalene ring system and the pyridine ring are oriented at a dihedral angle of 41.82 (4)°. In the crystal, weak C - H?O hydrogen bonds link the molecules related by translation along the a axis into chains. C - H?? interactions aggregate these chains into layers parallel to the ab plane. © Işiklan et al. 2013.

    4?,4?,6?,6?-Tetrachloro-2-(6-methylpyridin-2-yl) -1H,2H-spiro[naphtho[1,2-e][1,3,2]oxazaphosphinine-3,2?-[1,3,5,2,4,6] triazatriphosphinine]

    The title compound, C17H14Cl4N 5OP3, is a spiro-phosphazene derivative with bulky naphthalene and pyridine rings. The phosphazene and the six-membered N/O rings are in flattened-boat and twisted-boat conformations, respectively. The naphthalene ring system and the pyridine ring are oriented at a dihedral angle of 18.06 (8)°. In the crystal, weak ?-? stacking between the pyridine rings and between the pyridine rings and the naphthalene ring system [centroid-centroid distances = 3.594 (2) and 3.961 (2) Å, respectively] occur. Weak C - H?? interactions are also observed. These interactions link the molecules into a three-dimensional supramolecular network. © Işiklan et al. 2013.
