✦ Synopsis

The condensation reactions of N 2 O x (xZ2, 3) donor type bifunctional aminopodands 1-4 with hexachlorocyclotriphosphazatriene, N 3 P 3 Cl 6 , have been investigated and the partly substituted 5-8 novel spiro-cyclic phosphaza (PNP) lariat ethers, having various different ring sizes between 11 and 14-membered macrocycles, have been prepared. Compounds 5-8 are the first examples of the spiro-cyclic phosphaza (PNP) lariat ether derivatives consisting of the aminopodand precursors. Interestingly, in the macrocyclic rings of the compounds 5-8, there are four-centered (trifurcate) N-H/O/N-H/N hydrogen bonds. The relative radii of the ring inner-hole sizes for 5-8 are 1.14, 0.95, 1.14 and 1.38 A ˚. Salient futures of the spectral data ( 1 H-, 13 C-, 31 P-NMR, HETCOR, FTIR and MS) are presented. The molecular structures of compounds 7 and 8 were determined by X-ray diffraction techniques.
