Bidentate Groups

Displacement of Bidentate Groups. A kinetic study of the reaction of the [Pt(ox)2] anion with thiocyanate indicated the intermediacy of complexes containing uni-dentate oxalate ligands. Now the isolation of a salt of the [Pt(ox)2(SCN)2] - anion

Fig. 18. a-Hydroxycarboxylate binding of metal ions. In this case there is a strong tendency for chelation of the metal ion, although it may lie well out of the plane of the liganding bidentate group, (a) View onto OOC-C-OH plane and (b) view along OOC-C-OH plane.

It is interesting to note however that reaction occurs with siloxane groups at room temperature for silica samples pretreated at high temperatures. If the so formed monodentate (see reaction (C)) groups are close enough to a residual SiOH group, reaction may occur with the formation of bidentate groups on the surface. This...
