| Abstract: | The molar constants of paramagnetic birefringence (PBR) for the dimeric dysprosium(iii)d- anddl-tartrates, Dy2(d-Tart)(l-Tart)2– (1) and Dy2(d-Tart)2
2– (2) have been determined by means of pH-metric and PBR measurements. The simulation of the structure of the ligand and solvate environment has been carried out using the method of molecular mechanics (Dashevsky-Plyamovaty model, the MIND program). In addition to the four oxygen atoms from the ligand, each DyIII ion coordinates four molecules of water and a Na+ ion.Translated fromIzvestiya Akademii Nauk.
