Potentiometric, spectrophotometric and AM1d studies of the equilibria between silver(I) ion and diaza-crown ethers with anthraquinone moiety in various solvents

Complex formation and stability constants between the silver(I) ion and diaza-crown ethers with an anthraquinone moiety were determined in organic solvents. It was found that AgL+, AgL2+, Ag2L32+ and Ag3L22+ species were formed. Selected structures of the complexes were visualized at a semi-empirical level of theory.140
