The chlorophosphazenes (NPCl2)3-6 and the phenylchlorophosphazenes gem-N3P3Ph4Cl2 and gem-N3P3Ph2Cl4 react with pyrazole, 3-methylpyrazole, and 3,5-dimethylpyrazole to give (NPpz2)3-6, 3-5, 3,4, N3P3Ph4(Mepz)2, N3P3Ph4(Me2pz)2, and N3P3Ph2(Me2pz)4.Infrared and nmr spectroscopy show the pyrazolyl group to be an electron-withdrawing substituent on the phosphazene ring, resembling a halogen rather than an amino group.The pyrazolyl group also acts as a donor through its pyridinic nitrogen atom, both intramolecularly and in the formation of thecomplexes gem-N3P3Ph4(Me2pz)2*PdCl2, gem-N3P3Ph2(Me2pz)4*PdCl2, N3P3(Me2pz)6*2PdCl2, N3P3(Me2pz)6*2PtCl2, and N3P3(Me2pz)6*3PdCl2.No bonding between the metal and a nitrogen atom in the ring was detected.
