The unusual chemical shift of the sp2 hybridised phosphorus has been
noted previously for phosphametallocenes undergoing reactions with
strong electrophiles, but is not normally observed in classical η1-coordi-
nation to transition metal centres. See D. Carmichael, P. Le Floch, X. F.

potential tautomerisation process has been discussed: G. Manca, M. Ca-

of 1,3,2-diazaphosphole cations with soft transition metals are frequently
bimetallic; however, whilst a clear distinction appears between the “co-
ordinated” metal (Pd) and the metal that is integral to the ligand struc-
ture (Co) for the complexes described in this paper, the case of the
diazaphosphole cation is generally much less clearcut. For phospha-
metallocenes, phosphaferrocenes: B. Deschamps, J. Fischer, F. Mathey, A.
Mitschler, Inorg. Chem. 1981, 20, 3252–3259 (and phospharuthenocenes,
see: E. Muller, PhD Ecole polytechnique 2010) are known to undergo
nucleophilic attack at phosphorus by strong bases; the more electro-
philic half-sandwich phosphacymantrene complexes undergo addition
of less powerful nucleophiles (OH–, CN–), again at phosphorus. For fuller
details see, for instance, ref [19].

The difficulties in predicting the relative orientation of the rings in eg
ferrocene are well known: a) M. Bühl, S. Grigoleit, Organometallics 2005,
24, 1516. The potential surface for the rotation of phospholyl rings in
late transition metal 1,1′-diphosphametallocenes is also known to be
relatively flat: b) M. D. Su, S. Y. Chu, J. Phys. Chem. 1989, 93, 6043–6051

difference in orbital orientation can be clarified by inspection of some
of the critical orbitals given in the Supporting Information. See, for ex-
ample, the orientations of the lone pair rich combinations in orbitals 118
and 120 of 1M06, as compared with the sp3 lone pair rich combination
The nature of the formally sp2 lone pair in 1M06 was investigated through
NBO analysis: lying at –17.20 eV, it has 1.95e population and a composi-

tion of s: 66.2, p: 33.8 d: 0.1 % which represents a hybridisation of sp0.51

the corresponding phosphaferrocene 6M06 gave the analogous orbital
populated by 1.95e at –13.13 eV of composition s: 63.7, p: 36.2, d: 0.1 %
for an overall hybridisation of sp0.57. The data for the respective LUMO′s
are –7.17 eV, 95.6 % p-hybridisation for 1M06; –3.47 eV, 91.8 % p-hybridi-

An opposite, and quite strong, bond lengthening effect is generally ob-
served when phosphaferrocenes chelate to electrophilic (eg Pd) centres.
This is generally accepted to be the result of strong interactions between
the metal and the Fe–P bonds, which are high-lying relative to the corre-
sponding phosphorus lone pairs. For an orbital analysis, see ref [47].
