Abstract (EN): The coordination chemistry involved in the assisted transfer of Rh-III by interfacial coordination with 2,5,8-trithia[9],(2,9)1, 10-phenanthrolinophane (L) has been studied at the water/1,2-dichloroethane interface by cyclic voltammetry. The dependence of the half-wave transfer potential on the ligand and metal concentrations suggests the [Rh(L)Cl-2](+) formulation for the complex cation involved in the assisted transfer, In contrast, from the reaction of L in refluxing MeCN/water solution the [Rh(L)Cl][BF4](2).2MeCN compound has been isolated and structurally characterised. In the [Rh(L)Cl](2+) complex cation L acts as an N2S3 donor encapsulating the metal centre within a cavity having a square-based pyramidal geometry. A chloride ligand completes the distorted octahedral coordination sphere around the Rh-III ion.
