A series of M (II)(M= Cu, Zn, Cd, Pb) complexes with the physiologically active 2-acetylindan- 1, 3-dione were synthesized. All complexes were obtained with the metal to ligand ratio 1: 2. The presence of two water molecules in the inner coordination sphere of the Zn (II) and Cd (II) complexes was proven. The structure and coordination mode of the newly synthesized Cd (II) and Pb (II) complexes were investigated using NMR (13C CPMAS and 13C NMR in ...
