Coordination of silver(I) by N,N-diethyl-N′-benzoyl thiourea in solution and in the solid state

Article abstract of DOI:10.1002/zaac.19976230122

Silver(I) reacts in dioxane/water solution with N,N-diethyl-N′-benzoyl thiourea HL to give cationic, neutral, and anionic complexes depending on the pH value, the molar ratio of the reactants and their concentrations. The ligand in these complexes coordinates in various ways. Complex stability constants have been determined by pAg and pH potentiometry. Representative complexes have been isolated in the solid state. One of them is a cyclic tetramer [AgL]₄ the structure of which has been determined by X-ray diffraction.
