(EDDP) and N,N′-ethylenedianthranilic (EDA) acids have been studied by EPR and electronic absorption spectroscopy. The species taking part in the complexformation processes have been identified and structures proposed by previous equilibrium studies have been examined and discussed on the basis of the spectroscopic data. In particular, hydrolysis has been found to yield mononuclear and dinuclear hydroxo

IR, 1H NMR and 119Sn Mössbauer spectroscopy indicates that the ligands are bound only through oxgen. In most cases the carboxylates are bidentate and the tin five-coordinate. The Ph3Sn and Cy3Sn derivatives contain tetrahedral tin, with monodentate carboxylates.
