Résumé
The standard partial molar volumes have been determined for [(en)2ClCo(III)(don) Co(III)CL(en)2] Br4-[α-CDX]-rotaxane (Rotaxane) and its component compounds, [(en)2ClCo(III)(don)Co(III)Cl(en)2] Br4 (Co(III)-II), and α-CDX, in aqueous solution at 25°C Vo (Rotaxane) is smaller than the sum of Vo (CO(III)-II) and Vo (α-CDX) by about 28 cm3-mol−1. Some estimations were attempted; the number of methylene groups in the cavity of α-CDX, was estimated to be six and the number of water molecules expelled from α-CDX cavity by hydrocarbon chain of the Rotaxane, is around four.
