The first examples of ferrocene derived cyclocarbaphosphazenes have been sy
nthesized by the reaction of Fe(eta-C5H5)-[eta-C5H4CH2P(S) (CH2OLi)(2)] wit
h (RR'NCN)(2)(Cl2PN) [RR'N = Me2N and PhCH2(Me)N]. The crystal structure of
the spirocyclic compound {Fe(eta-C5H5)-[eta-C5H4CH2P(S) (CH2O)(2)PN)]}(Me2
NCN)(2) has been determined and shows an axial orientation of the ferroceny
lmethyl group with respect to the six-membered chair form of the spirocycle
