The coordination geometry of silver(I) and copper(I) complexes in their crystals are greatly influenced by the solvent of crystallization, type and number of ligands, and the counter ion used. These coordination numbers vary from 2 to 6. In this thesis, the synthesis of silver(I) and copper(I) complexes with different geometries, which have been obtained under different experimental conditions and characterized by elemental analyses, IR, UV-Vis and 1 H-NMR spectroscopies, are reported.
