    Notes: 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.

    Notes: Abstract Structures of the following compounds have been solved: tris(2-thio-6-picoline N-oxide)cobalt(III), [Co(6MOS)3], orthorhombic, Pca21, a = 17.871(3), b = 14.061(2), c = 15.964(2) Å, V = 4011(1) Å3, Z = 8, and μ = 1.193 mm−1; bis (2-thio-6-picoline N-oxide)nickel(II), [Ni(6MOS)2], orthorhombic, Pbca, a = 15.602(8), b = 13.606(4), c = 13.348(8) Å, V = 2833(4) Å3, Z = 8, and μ = 1.655 mm−1; bis(2-thio-6-picoline N-oxide)copper(II), [Cu(6MOS)2], orthorhombic, Pbca, a = 13.914(5), b = 12.984(5), c = 15.663(6) Å, V = 2830(2) Å3, Z = 8, and μ = 1.836 mm−1; and bis(2-thio-6-picoline N-oxide)zinc(II), [Zn(6MOS)2], triclinic, P − 1, a = 7.9737(8), b = 11.7786(9), c = 7.9206(8) Å, α = 104.502(7), β = 104.495(8), γ = 93.445(8)°, V = 691.3(1) Å3, Z = 2, and μ = 2.106 mm−1. The steric effect of the methyl group in the six-position of the N-oxide ring is considered in comparing these structures to complexes of 2-thiopyridine N-oxide.
