The partial molal volumes, \bar<I>V</I><SUP>°</SUP>, of [M(phen)<SUB>3</SUB>]Cl<SUB>2</SUB> (M=Fe(II), Co(II), Ni(II), Cu(II), and Zn(II)) and 1,10-phenanthroline were determined from density measurements at 25 °C. From the values for \bar<I>V</I><SUP>°</SUP> of [M(phen)<SUB>3</SUB>]<SUP>2+</SUP>, M<SUP>2+</SUP> and phen the volume changes for complex formation of [M(phen)<SUB>3</SUB>]<SUP>2+</SUP>, Δ\bar<I>V</I><SUP>°</SUP>, were caluculated. Values for \bar<I>V</I><SUP>°</SUP> of [M(phen)<SUB>3</SUB>]Cl<SUB>2</SUB> varied from 445.1 cm<SUP>3</SUP> mol<SUP>−1</SUP> for [Fe(phen)<SUB>3</SUB>]Cl<SUB>2</SUB> to 458.1 cm<SUP>3</SUP> mol<SUP>−1</SUP> for [Zn(phen)<SUB>3</SUB>]Cl<SUB>2</SUB> and were in the order, [Fe(phen)<SUB>3</SUB>]<SUP>2+</SUP><[Co(phen)<SUB>3</SUB>]<SUP>2+</SUP>>[Ni(phen)<SUB>3</SUB>]<SUP>2+</SUP><[Cu(phen)<SUB>3</SUB>]<SUP>2+</SUP><[Zn(phen)<SUB>3</SUB>]<SUP>2+</SUP>. The Δ\bar<I>V</I><SUP>°</SUP> of [Fe(phen)<SUB>3</SUB>]<SUP>2+</SUP> was significantly small, 4.7 cm<SUP>3</SUP> mol<SUP>−1</SUP>. While those of other metal chelate ions were similar values, <I>ca.</I> 20 cm<SUP>3</SUP> mol<SUP>−1</SUP>. The smaller Δ\bar<I>V</I><SUP>°</SUP> of [Fe(phen)<SUB>3</SUB>]<SUP>2+</SUP> is considered to be due to the spin change from the high-spin aqua ion, [Fe(OH<SUB>2</SUB>)<SUB>6</SUB>]<SUP>2+</SUP>, to the low-spin complex ion, [Fe(phen)<SUB>3</SUB>]<SUP>2+</SUP>.
