SYNTHESIS AND CRYSTAL STRUCTURE OF cis-equatorial-Na[Rh(Hed3ap)Cl]∙2.22H2O COMPLEX

Abstract

This complex was prepared by the procedure used to make Rh(III) complexes with hexadentate edta-type of ligands [1]. After elution with 0.1 M NaCl, five yellow bands were detected on the chromatographic column. All bands were separated, evaporated, desalted using Sephadex G-10 resin and evaporated to ca. 5 ml. After the addition of 3 to 4 ml of ethanol, the solutions were left in a refrigerator for several days. After several days, the yellow crystals of the band IV were col-lected and air-dried. The obtained crystals represent a complex of cis-equatorial-Na[Rh(Hed3ap)Cl]∙2.22H2O.
