The crystal and molecular structure of tetrakis{(isopropylthio)acetato}bis(quinoline)dicopper(II) (<B>1</B>), bis(dibenzylamine)bis{(ethylthio)acetato}copper(II) (<B>2</B>), and bis{(isopropylthio)acetato}tris(isoquinoline)copper(II) (<B>3</B>) were determined by the X-ray diffraction method. The final <I>R</I> values obtained are 0.041, 0.055, and 0.078 for <B>1</B>, <B>2</B>, and <B>3</B> respectively. <B>1</B> is green in color and is orthorhombic with the space group Pcab. It has a dimer structure similar to that of the copper(II) acetate hydrate, where four (alkylthio)acetate liagnds bridge both copper(II) atoms. <B>2</B> is violet in color and is monoclinic with the space group A2/a. It has a square-palnar geometry, and no atoms are coordinated to the copper(II) atom from the axial direction, probably because of the steric effect of the large dibenzylamine molecules. <B>3</B> is blue in color and is triclinic with the space group P\bar1. It has potentially a hepta-coordinate geometry, where one nitrogen atom and two oxygen atoms ligate from the axial direction of the CuN<SUB>2</SUB>O<SUB>2</SUB> plane.
