First of all, a warm welcome to all the new group members (for details and new pictures see the team section)!
We have
recently reported on the utility of multifunctional, k1Si:k3S-coordinated
tris(methimazolyl)silanide ligands [Si(mtMe)3]- for the stabilisation of a triangulo palladium cluster [Pd3{Si(mtMe)3}2]
(see picture) consisting of very unusual m3-capping SiR3 donors. Differences to
the corresponding platinum chemistry were supported by NMR spectroscopy and DFT
calculations.

The
preparation and structures of new tris(pyrazolyl)methane and tris(pyrazolyl)methanide complexes have been reported, together with mechanistic and synthetic studies
of their interconversions and solution dynamic behavior. This work was
performed in collaboration with the Mountford group (Oxford).

In a recent full-paper (Dalton Trans. 2009, 5612 - 5626; "Hot Article") we
reported on synthetically valuable precursor compounds
as well as the synthesis and some reactivity studies of a novel ambidentate tris(pyrazolyl)silanide (MeTpsd). This silicon-containing Janus-head ligand can either separately or simultaneously
act as κ1Si-
or κ3N-coordinating
ligand (see inside front cover of issue 29)
