Abstract Densities and ultrasonic velocities were measured at 25°C for aqueous solutions of bipyridine and phenanthroline complexes [M(bpy)3]Cl2 and [M(phen)3]Cl2 (M=Fe, Co, Ni, and Cu, bpy=2,2′-bipyridine, and phen=1,10-phenanthroline), and chlorides of these metals. The partial molar volumes V 2 o and partial molar adiabatic compressibilities K s o were calculated. For the complex ions, [M(bpy)3]2+ and [M(phen)3]2+, electrostatic interactions with the solvent are not nearly as important as effects due to the hydrophobic ligands bpy and phen. The relationship between V 2 o and K s o of the complex ions and common metal ions are examined.
