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]

Abstract: In the title spiro-phosphazene derivative, C33H46N9OP3, 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...[pi] interactions aggregate these chains into layers parallel to the ab plane.
