Adducts of silicon tetrafluoride with aminocyclophosphazenes: synthesis and characterization

Abstract

Stable solid adducts of SiF4 with the following aminocyclophosphazenes have been synthesized: N3P3(NHCH2CH2NH)(NMe2)4, (1); N3P3(NHCH2CH2NH)Cl4, (2); N3P3(NMe2)4Cl2, (3); N3P3(NHMe)6, (4); N3P3(NMe2)6, (5); N4P4(NHMe)8, (6); N4P4(NMe2)8, (7); and N4P4(NHBut)8, (8). They have been characterized by elemental analysis, i.r., and n.m.r. (1H, 31P, and 19F) spectroscopy. The composition of the adducts varies depending on the ring size and also on the nature of the substituents on the phosphorus. The number of SiF4 molecules accommodated by the ligands is larger when the ring size is large, while it is less when the ligands contain chlorine. Except in the cases of ligands (1) and (2), bonding is through the ring nitrogens. With (1), both exocyclic nitrogen and ring nitrogen atoms, and with (2) only exocyclic nitrogen atoms, participate in co-ordination. In these two cases the silicon is six-co-ordinated, while in the other cases it is five-co-ordinated.
