Article abstract of DOI:10.1007/BF00745984

An x-ray structural study of the complexes (I) and *H2O (II) has been carried out (λMoK_α, Syntex P2₁ automatic diffractometer, heavy atom method, refinement by the method of least squares in the anisotropic approximation).The crystals of complex I are orthorhombic, a=6.297(5), b=8.987(6), c=23.771(15) Angstroem, α=β=γ=90 deg, d_calc=2.26 g/cm³, Z=4, V=1345.26 Angstroem³, space group P2₁2₁2₁, R=0.067.The crystals of complex II are monoclinic, a=6.193(7), b=9.067(17), c=14.218(20) Angstroem, β=103.749 deg, d_calc=1.58 g/cm³, Z=2, V=775.58 Angstroem³, space group P2₁/a, R=0.068.The crystal structures of complexes I and II consist of isolated dinuclear molecules.The Ag-Ag distances are 2.92 and 2.90 Angstroem respectively.The carboxylate groups act as bidentate bridging ligands, forming eight-membered rings.The average Ag-O distance is 2.21 Angstroem.The crystal structures of complexes I and II differ in that in the case of complex II, hydrogen bonds (O...O 2.699 Angstroem) are frmed between the water molecule and the OH group of the para-hydroxybenzoate ligand.
