概要
- 論文の詳細を見る
New cobalt(III) complexes with 2,4-pentanediaminetetraacetate (2,4-ptnta<SUP>4−</SUP>) have been prepared. The optically active 2,4-ptnta<SUP>4−</SUP> (RR or SS) forms a sexadentate complex and determines the absolute configuration around the metal ion. The <I>meso</I>-2,4-ptnta<SUP>4−</SUP> (RS) coordinates to the metal ion as a quinquedentate with a free acetate branch. Such stereospecific formations of sexa- and quinquedentate complexes from the optically active and the <I>meso</I> 2,4-ptnta<SUP>4−</SUP> have been attributed to the steric regulation coming from the methyl groups on the α-carbon atoms.
