and related complexes of the zinc-group and p-block elements -
We have a long-standing interest in the synthesis, multinuclear
magnetic resonance spectra and structures of species containing an
adamantane-like cage of the type ”The
crystallisation and packing of [Cr(C2O4Ag(PPh3)2)3]
(Ph3P/Ph33PO) (MeNO2)4”. Dean,

(m
-ER)6M4 (E = S,Se,Te; M = Zn,Cd,Hg; R = aryl
or alkyl), in which there may be a variety of terminal ligands
attached to M. These complexes are interesting for many reasons: the
RS--bridged complexes are structural and spectroscopic models for
biological binding sites; all the complexes exhibit an interesting
form of configurational isomerism; the tetranuclear aggregates may
be converted into larger aggregates or (with appropriate linkers)
form the basis for open, zeolite-like lattices, etc. The
coordination chemistry of potential linkers is an area of active
interest. Our work on these adamantanoid species has been part of a
more general study of the chemistry of ligands in which at least one
of the donor atoms is a chalcogen. An additional area of current
interest is in the chemistry of such ligands with the p-block
elements. Relatively little is yet known about complexes of these
elements with Se-donor ligands, and even less about complexes with
Te-donor ligands, although solid selenides and tellurides are very
important technologically. Therefore we are carrying out exploratory
synthetic chemistry in this area. Along the way, we have, with
collaborators, been spending a lot of effort on complexes of
thiocarboxylates, which are possible precursors to element sulfides
in technologically-desirable forms. In addition, some of our
compounds show interesting packing motifs in the solid state and we
have been collaborating with other colleagues in this general
area. Selected Publications
