  used, for example, to introduce chelating ligands into transition metal complexes. The structures of the compounds have been determined by X-ray diffraction. When there is a phenyl substituent on the sulfur atom, the metal derivatives are isomorphic dimers, involving three fused four-membered rings in a step-shaped structure. The higher the atomic number of the metal, the stronger is the η-coordination

  The syntheses and solid state structures of (THF2M(NSiMe3)(2)SPh}(2)] (M=Ca, 1; M=Sr, 2; M=Ba 3) and (THFnM(NSiMe3)(2)SN(SiMe3)(2)}(2)] (M = Mg, n = 0, 4; M = Sr, n = 1, 5) are presented. Although the (Me3Si)(2)NS(NSiMe3)(2)(-) anion resembles to a large extent the structural features of the PhS(NSiMe3)(2)(-) anion, careful examination of structural parameters reveals marginal differences in their coordination to alkaline earth metal dications. Above all, bonding to the metals is predominantly ionic, but the nature of the small covalent contribution differs in both anionic systems. Strictly planar SN2M four-membered rings in 1, 2 and 3 indicate exclusively sigma-bonding of the PhS(Me3SiN)(2)(-) anion towards the alkaline earth metal. The SN2 moiety of the (Me3Si)(2)NS(NSiMe3)(2)(-) anion seems to be more pi electron rich. The metal is not located in the plane of the N-S-N chelating ligand, but is displaced from the plane towards the sulphur atom to interact with the pi electron density. This effect is caused neither by the steric demand of the ligand nor by packing effects but is induced by the different electronic nature of the ligand. Structural comparisons to related systems substantiate these findings. The size and polarizability of barium, in particular, enables this metal to interact with the non-directed pi electron density of the SN2 fragment. (C) 1998 Elsevier Science S.A.
