用邻二硝基二（乙二胺）-钴（III）钙盐将Co（III）、Cr（III）和Rh（III）的三（硫代）络合物分离成光学异构体。正如从氧和硫与铬的键合的相似性所预期的那样，与这种金属的络合物在溶液和固体状态下迅速外消旋化。Co（III）和Rh（III）配合物在固态下在几周内和90 ℃水溶液中在10分钟内都没有明显的旋转损失。虽然Fe（III）化合物具有指示自旋配对的磁矩（2.35 BM），但解析的尝试没有结果。
The tris-(thio-oxalato) complexes of Co (III), Cr (III) and Rh (III) have been separated into the optical isomers through the calcium c «-dinitrobis-(ethylenediamine)-cobalt (III) salts. As anticipated from the similarity of the bonding of oxygen and sulfur to chromium, the complex with this metal racemized rapidly in solution and in the solid state. The Co (III) and Rh (III) complexes showed no significant loss of rotation in the solid state in severalweeks nor in aqueous solution at 90 in 10 min. All were decomposed by light. Though the Fe (III) compound has the magnetic moment(2.35 BM) indicative of spin-pairing, attempts at resolution were fruitless.
