Abstract

The title compound, C17H14Cl4N5OP3, 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 π–π 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⋯π inter­actions are also observed. These interactions link the molecules into a three-dimensional supramolecular network.

“…It has been observed that N 3 P 3 Cl 6 and bifunctional reagents give spiro-, ansa-, bino-and open-chain (vibrational) products in the reactions. There is limited research on the reactions between N 3 P 3 Cl 6 and N-substituted amino alcohols (Begeç, 2022;Beşli et al, 2007;Chandrasekhar et al, 1984;Coles et al, 2004;Eçik et al, 2012;Işıklan, Sayın, et al, 2016;Işıklan et al, 2013aIşıklan et al, , 2013bIşıklan, Yıldırım, et al, 2016). Microwave-assisted synthesis is a new concept in the synthetic chemistry.…”
