Abstract
Abstract The crystal structure of the acetone adduct of copper(II) (2,4-dichloro-5-methylphenylthio)acetate has been determined by single crystal X-ray diffraction and refined by least squares to 0.051 for 3701 “observed” reflections. Crystals of the compound are triclinic, space group P 1 with one dimer in a cell with a = 8.357(1), b = 12.502(2), c = 13.721(2) A, α = 107.20(1), β = 96.09(1), γ = 104.94(1)°. The complex is a tetracarboxylate bridged dimer of the copper acetate hydrate type, with a CuCu separation of 2.646(1) A and a mean CuO (equatorial) distance of 1.961(4) A, while the axial positions of the dimer are occupied by coordinated acetone molecules [CuO, 2.206(3) A]. X-ray crystal data and the results of chemical analyses are also presented, indicating that a second chemical polymorph has both acetone and water molecules, with a similar dimeric structure but having solvated acetone.
