Abstract

Pyrolysis under air at 800 °C, of the cyclic N3P 3[OC6H4PPh2•Mn(CO) 2(?-MeC5H4)]6 (1) and the polymer {[NP(O2C12H8)] 0.5[NP (OC6H4COOPr n )(OC6H4 PPh2•Mn(CO)2(?-MeC5H4))] 0.5} n (2) phosphazene with pendant OC6 H 4PPh2•Mn(CO)2 (?-MeC5 H4) units affords nanostructured Mn2 P2O 7. The morphology of the pyrolytic products is highly dependent on the phosphazene support. Dense structures were observed from pyrolysis of cyclic (1) while most porous materials were obtained from pyrolysis of polymer (2). The new polymeric complex (2) was prepared from reaction of the phosphine containing polymer {[NP(O2 C12 H8)] 0.5 [NP(OC 6H4COOPr n )(OC 6 H4 PPh2)] 0.5} n and the photochemically generated [Mn(THF)(CO) 2(?-MeC5H 4)] and was fully characterized. © 2009 Springer-Verlag.
