The coordination chemistry of silver has historically been centred on the reaction of silver(I) ions with N-donor ligands and halides. However, an extensive chemistry now exists for P- and S-donor ligands, whilst for O-donor ligands only weak complexes are generally formed and they have been studied in much less detail. Based on the reactivity and stability of its coordination complexes, the silver(I) ion has been characterized as a class B or soft acid, for which the following stability order is observed N P>As>Sb 0 S Se Te FComparative studies between ligands with these donor atoms allowed the relative stability of silver bonds to be determined as P > S > N > O. 

The product complex is a bridged dinuclear Lu-Li compound with a puckered LuS2Li unit and Lu-S distances of 2.709 and 2.723 A. Complexes of the type Cp Yb(ER)(L), where R = organic group, E = O, S, Se, Te, L = Lewis base have been characterized and the structure of the complex [Cp Yb(SPh)(NH3)] shows the Yb atom is at the centre of a distorted tetrahedron, consisting of one sulfur, one nitrogen and the Cp ring centroids [175],...
