Abstract:	Apparent molar volumes have been determined by density measurements of aqueous solutions for a series of salts [Co(L)₃]X₃, where X=Cl^– and Br^– and L¹=1,2-diaminoethane (en), L²=1,2-diaminopropane (pn) and L³=1,3-diaminopropane (tn) at 15°C and 5°C. Apparent molar volumes at infinite dilution for the complex cations at 0°C are estimated. The resulting values are related to the structure of solvent water molecules around the ions.

Keywords:	Density apparent molar volume aqueous solutions trisethylenediaminocobalt(III) chloride and bromide tris-propylene-diaminocobalt(III) chloride and bromide tris-trimethylenediaminocobalt(III) chloride and bromide hydrophobic interaction
