Metal-(phenylthio)aikanoic acid interactions. VII the crystal structures of catena-[(phenylthio)ethanoatosilver(I)] and tetrakis-μ-[2-(2-chlorophenylthio)-2-methyl- propanoato- 0, 0′]-bis[aquacopper(II)]

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) A. 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-O, 2·454(3), 2·230(4) Å], giving the two-dimensional structure. Complex (2) is a tetracarboxylate bridged dimer of the copper(II) 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 P1 with two dimers in a cell of dimensions a 7·340(2), b 14·863(5), c 22·963(8) Å a 104·33(2), β 98·18(2), γ 102·18(2)°. Final residuals for (1) and (2) were 0·45 and 0·051 for 1688 and 3467 observed reflections respectively.
