Abstract
The host Ni(4-mepy)4(NCS)2, I, forms isomorphous 1:1 inclusion compounds with many monocyclic aromatic guests. In continuing attempts to determine the basis for the selectivity shown by I towards pairs of such guests, distribution data between solid and liquid phases were reported for seven ternary systems at room temperature. These consist of I, p-xylene, and each of the following in turn: p-bromotoluene, p-chlorotoluene, p-fluorotoluene, p-dichlorobenzene, 4-methylpyridine and benzene, as well as the system I—p-chlorotoluene—p-dichlorobenzene. The results, as well as those already published, were reviewed.
