本文报道了市售的双金属配合物的顺式和反式-1，2-二氨基环己烷（cis-和trans-cis）的制备分离方法，该方法是通过每个双金属配合物与Ni（II）离子的选择性络合物形成来实现的。顺式和反式双金属离子分别以黄色Ni（cis-dopamine）_2Cl_2和紫色Ni（trans-dopamine）_2（H_2O）_2Cl_2络合物形式分离，并在适当条件下优先沉淀。
The preparative separation method of cis- and trans-1,2-diaminocyclohexane (cis- and trans-dac) of commercially available dac preparations is reported by means of the selective complex formation of each dac with Ni(II) ions. cis- and trans-dac were separated as yellow Ni (cis-dac)2Cl2 and violet Ni(trans-dac)2(H2O)2Cl2 complexes respectively, which were precipitated preferentially under the appropriate conditions.
