This paper gives an overview of the structural chemistry of silver(I) coordination complexes. The main discussion is on the halide complexes (F −, Cl −, Br −, I −) but included are also the pseudo-halides (CN −, SCN −) and the classical non-coordinating anions (NO 3 −, ClO 4 −, BF 4 −, PF 6 −) and oxy-anions (NO 3 −, H 3CCO 2 −, F 3CCO 2 −, F 3CSO 3 −, etc.). The main focus is on complexes of these silver(I) salts with phosphine ligands, but where relevant the chemistry of other donor ligands is also reviewed. Coordination complexes of silver(I) halides show a rich variation of structural types. The type of structure depends on the stoichiometry of the ligand to silver in the reaction mixture, as well as reaction conditions. Other factors influencing the structure of these complexes include the halide or pseudo-halide ligands used as counterion and the type of solvent.
