Diaquabis(-4-hydroxybenzenecarboxylato-²O,O')disilver(I)(Ag-Ag) tetrahydrate

Y. Wang and N. Okabe

Abstract: The title complex, [Ag₂(C₇H₅O₃)₂(H₂O)₂]·4H₂O, is a centrosymmetric bis(carboxylato-²O,O')-bridged binuclear dimer with a strong Ag-Ag interaction. Each Ag^I atom has a four-coordinate square-planar geometry, in which it is bonded to two carboxylate O atoms, one water O atom and the other Ag^I atom. All the coordinated and uncoordinated water molecules are disordered; they form a cluster around the dimer through intermolecular hydrogen-bond networks, linking the complex molecules to each other.
