A new type of silver(I) coordination complex derived from silver(I) perchlo
rate (or triflate) and polycyclic aromatic compounds is reviewed. Structura
l studies by single-crystal X-ray diffraction have shown that all compounds
contain extended one- to three-dimensional structures in which several met
al atoms are sandwiched between two fused polycyclic systems. Special atten
tion is paid to the combination of the plasticity of the metal ion, coordin
ative versatility of the aromatic ligand, solvent effect and the nature of
the counteranions for designing metal complexes with a wide range of infini
te frameworks. (C) 2000 Elsevier Science S.A. All rights reserved.
