✦ Synopsis

In a study of tllc application of paper chromatography to tllc separation of stcrco-isomcricinorganiccoml~ounds, wccstahlishccl, as early as 1954, that in this way inorganic isomcric cis-lrnm compounds can bc rcsolvcd into the componentsl. In the same year, 'L',\Xl,\hlo*ro, NAKAIIARA AND 'I'SUCI~IDA~ published a paper in wliich the alteration of the I'r; values wit11 the number of nitro groups in tllc coinplcs cobalt ammincs was investigated.

In this study tlicy clctcrmincd the I<F values of cis ancl lva~s [Co(NH,),,(NO,),]Cl, but gave no indication of attempts to separate the cis and Irtr~ forms.

Following tlic initial investigations, WC have so far scparatcd I2 pairs of isomeric compounds belonging to the group of clcctrolytes with complex cations, i.e.* : I.
