μ-Biphenyl-4,4′-dicarboxylato-bis{[2-(piperidin-1-yl)ethanamine]silver(I)} dihydrate

The title complex, [Ag-2(C14H8O4)(C7H16N2)(2)]center dot 2H(2)O, consists of a biphenyl-4,4'-dicarboxylate-bridged centrosymmetric dinuclear silver(I) complex and two uncoordinated water molecules. The Ag atom is three-coordinated by two N atoms of 2-(piperidin-1-yl) ethanamine and one O atom of biphenyl-4,4'- dicarboxylate, forming a distorted T-shaped coordination environment, the distortion being caused by the strain created by the five-membered chelate Ag - N - C - C - N ring. In the crystal structure, molecules are linked through intermolecular N - H center dot center dot center dot O and O - H center dot center dot center dot O hydrogen bonds, forming layers parallel to the bc plane.
