<jats:title>Abstract</jats:title> <jats:p>A new series of binuclear copper(II) complexes with 1,3-bis(hydroxymethyl)-2-imidazolidinethione, [Cu(RCOO)(HL1)]2 (where R = CH3 (1), C6H5 (2), 2-CH3C6H4 (3), 4-CH3C6H4 (4), 2-ClC6H4 (5), and 2-BrC6H4 (6)), and with 1-hydroxymethyl-3-methyl-2-imidazolidinethione, [Cu(RCOO)(L2)]2 (where R = CH3 (7), 2-CH3C6H4 (8), and 4-CH3C6H4 (9)), have been prepared. The magnetic susceptibility data of complexes 1—9 conform to the usual dimer equation with the −2J values ranging from 227 to 992 cm−1. Crystal structure analyses of 3, 4, 7, and 9 revealed that two copper atoms are linked by two alkoxo-bridges with separations of 3.015(3)—3.069(3) Å in each complex. The coordination around each copper atom of the complexes is essentially a square planar configuration with one sulfur and two alkoxo-oxygen atoms of HL1 or L2 and one oxygen atom of carboxylates. Each alkoxo-group asymmetrically bridges with the Cu1–O1 bonds (1.90—1.92 Å), which are shorter than the Cu1′–O1 bonds (1.93—1.97 Å). The −2J values for complexes 3, 4, 7, and 9 are much better correlated with the Cu1′–O1 bond distances than with the alkoxo-bridging Cu1–O1–Cu1′ angles.</jats:p>
