• The crystal and molecular structure of the title complex has been determined by the X-ray diffraction method. The crystal was triclinic, space group P\bar1, <I>a</I>=7.554(1), <I>b</I>=9.001(1), <I>c</I>=5.345(1) Å, α=104.83(1), β=99.20(1), γ=71.02(1)°, <I>Z</I>=1, <I>D</I><SUB>X</SUB>=1.684(1), <I>D</I><SUB>m</SUB>=1.69(1) Mg m<SUP>−3</SUP>, μ(Mo <I>K</I>α)=2.03 mm<SUP>−1</SUP>, and the final <I>R</I> value was 0.030 for 1818 reflections. The molecular arrangement has a center of symmetry and has a slightly distorted octahedral configuration around the central copper(II) atom; each ethylthioacetato ligand forms a chelate ring by coordinating through a sulfur atom and a carboxyl oxygen atom, and two water molecules are also coordinated to the central metal. The solid complex is deep green, different from the diaquabis(alkylthioacetato)copper(II) complexes of the higher alkyl groups (number of C≥3), and it is likely due to the CT band caused by the strong copper–sulfur bond in the complex.
