Abstract
The reaction of HN[P(NMe2)2NSiMe3]2 with NaH and KH in 1 : 1 molar ratio yielded a dimer {NaN[P(NMe2)2NSiMe3]2}21 and a polymer {KN[P(NMe2)2NSiMe3]22 with a zigzag chain structure, respectively. The reaction of Ca[N(SiMe3)2]2·2thf (thf = tetrahydrofuran) with the phosphazene in 1 : 2 molar ratio in hexane resulted in the formation of a monomeric spirocyclic phosphazene complex Ca{N[P(NMe2)2NSiMe3]2}23 where the mode of chelation is tridentate. The crystal structures of 1–3 have been determined.
