Abstract Structures of two binuclear copper(II) complexes with sulfato bridges and tridentate 2-acetylpyridine 3-azacyclothiosemicarbazone ligands have been solved. The complexμ-sulfato-bis{(2-acetylpyridine 3-hexamethyleneiminyl-thiosemicarbazonato)copper(II)} N,N-dimethylformamide, [Cu(Achexim)]2SO4·DMF, has the following structural properties: triclinic, P1¯(#2), a = 12.314(4), b = 15.885(4), c = 10.959(4) Å, α = 103.25(2), β = 103.60(2), γ = 109.94(2)°, V = 1843(2) Å3, and Z = 2; for μ-sulfato-bis{(2-acetylpyridine 3-piperidylthiosemicarbazonato)copper(II)}chloroform, [Cu(Acpip)]2SO4·CHCl3: triclinic, P1¯(#2), a = 11.657(1), b = 17.101(2), c = 10.338(1) Å, α = 98.51(1), β = 109.294(7), γ = 107.016(9)°, V = 1790.3(4) Å3, and Z = 2. The size of the azacyclo ring significantly affects the stereochemistry of these binuclear complexes.
