The X-ray crystal structure of the ligand I-4[(C6H5)(3)GeCH(o-CH3OC6H4)CH2COOH] delineate four coordinated germanium atom with a peculiarity of having a molecule of solvent (CHCl3)The chiral center in the synthesized compounds was identified on the basis of H-1 NMR data and measurements of angle of rotations.
