Abstract A convenient technique is described to determine reaction volumes by means of direct dilatometry. Reaction volumes were determined for the following complexation reactions: formation of monoamminenickel(II) in water (−0.1±0.5 cm3-mol−1); formation of the 1:1 nickel(II) complex with isoquinoline in methanol and ethanol (3.2±0.1 and 1.1±0.1 cm3-mol−1, respectively); formation of the 1:1 isothiocyanatoiron(III) complex in water, Me2SO, and DMF (8.9±0.2, 12.4±0.7, and 25.1±0.3 cm3-mol−1, respectively); formation of the 18-crown-6 potassium complex in water (10.9±0.2 cm3-mol−1). We discussed these values in terms of electrostriction and molecular size.
