Summary on Grant Application Form
Preliminary results have demonstrated that monosulfonated triphenylphosphine [TPPMS, PPhz(CeH,SOs -3)] and its complexes can be incorporated into hydrogen bonding networks via interactions between the sulfonate groups and guanidinium cations. We seek to extend this work by forming bilayer structures in which coordinatively unsaturated metal centres bearing two TPPMS ligands serve to bridge between guanidinium sulfonate (GS) layers. Compounds such as [C(NHz),][IrCI(CO)(TPPMS)z] will be structurally characterised, and their reactions with small molecules able to bind in the vacant coordination site, such as SOz, CO and Oz, studied. The reactions of the complex anions in solution will also be assessed, and the structures of the guanidinium salts of the solution products will be compared to those from the solid state reactions. Both new and previously reported TPPMS complexes will be prepared, and the chemistry of the new compounds will be compared to their PPha analogues. The effect of the canon on solid state structure will also be examined. The potential to incorporate other sulfonated ligands into GS arrays will be determined -such ligands include phosphines with a different number or orientation of sulfonates, and nitrogen donor ligands such as sulfonated 2,2'-bipyridyl. Finally, substituted guanidinium derivatives will be prepared to assess whether one- or zero-dimensional arrays can be formed in an analogous manner to the melamine-cyanuric acid system.
