The reactions of hexachlorocyclotriphosphazatriene, N ₃ P ₃ Cl ₆ , with N ₂ O ₂ -donor type coronands, Ph2[OR ₁ O][CH ₂ NHR ₂ NHCH ₂ ] [R ₁ = (CH ₂ ) ₃ , R ₂ = (CH ₂ ) ₃ (1), R ₁ = (CH ₂ ) ₃ , R ₂ = (CH ₂ ) ₄ (2), R ₁ = (CH ₂ ) ₄ , R ₂ = (CH ₂ ) ₄ (3)], give monotopic spiro-crypta phosphazene architectures, N ₃ P ₃ Cl ₄ {Ph ₂ [OR ₁ O][CH ₂ NR ₂ NCH ₂ ]) [R ₁ = (CH ₂ ) ₃ , R ₂ = (CH ₂ ) ₃ (4), R ₁ = (CH ₂ ) ₃ , R ₂ = (CH ₂ ) ₄ (5) and R ₁ = (CH ₂ ) ₄ , R ₂ = (CH ₂ ) ₄ (6)], respectively. The reaction of 4 with excess pyrrolidine leads to the formation of geminal N ₃ P ₃ Cl ₂ (C ₅ H ₅ N) ₂ {Ph ₂ [O(CH ₂ ) ₃ O] [CH ₂ N(CH ₂ ) ₃ NCH ₂ ]} (7). The ³¹ P-NMR spectra of 5 and 6 indicate that these compounds have anisochronism. The structures of 5, 6 and 7 were investigated by X-ray crystallography. For 7, the sums of the bond angles around the N atoms were 348·6(2)° and 349·7(2)° indicating that the N atoms have pyramidal configurations and are stereogenic. The relationship between the chemical shift values δP _(spiro) and the Δ(P-N) (electron density transfer parameters) of 4, 5, 6, 7 and the analogous compounds as well as the relationship between the Δ(δP) values and the above mentioned Δ(P-N) are presented respectively. In addition, the relationship between the endocyclic NPN bond angles of these compounds and the ³¹ P-NMR chemical shifts of the spiro-phosphorus atoms were investigated. The spectroscopic and structural investigations of the compounds were made by elemental analyses, MS, FTIR, one-dimensional ¹ H-, ¹³ C-, ³¹ P-NMR, DEPT and two-dimensional COSY, HETCOR, HMBC, homo- and heteronuclear correlation techniques.
