Metal (Phenylthio)Alkanoic Acid Interactions. VII. The Crystal Structures of catena-[(Phenylthio)ethanoatosilver(I)] and Tetrakis-μ-[2-(2-chlorophenylthio)-2-Methyl-Propanoato-O,O']-bis[aquacopper(II)]

Abstract

Metal complexes of two (phenylthio) alkanoic acids have been prepared and their structures determined by X-ray diffraction. catena-[( Phenylthio ) ethanoatosilver (1)] (1) forms crystals which are orthorhombic, space group Pccn, Z 8 and a 26.772(8), b 10.479(3) c 6.007(1) Å. The polymer structure consists of a distorted trigonal pyramidal AgO₃S repeating unit with coordination in the trigonal plane by a bidentate chelate thioethanoate group [Ag-O, 2.508(3); Ag-S, 2.513(2) Å]. The third position in the plane and the axial position are occupied by bridging carboxylate oxygens [Ag-0, 2.454(3), 2.230(4) Å], giving the two-dimensional structure. Complex (2) is a tetracarboxylate bridged dimer of the copper(11) ethanoate hydrate type, with a Cu-Cu separation of 2.624(2) Å and Cu-OH₂ (axial) distances of 2.155(7) and 2.182(6) Å. Crystals are triclinic, space group PI with two dimers in a cell of dimensions a 7.340(2), b 14.863(5), c 22.963(8) Å; α 104.33(2), β98.18(2), γ 102.18(2)º. Final residuals for (1) and (2) were 0.045 and 0.051 for 1688 and 3467 observed reflections respectively.
