(μ-biphenyl-4,4′-dicarboxylato)bis[(2-amino-pyridine)silver(I)]

The title compound, [ Ag-2( C14H8O4)( C5H6N2) (2)], is a dinuclear Ag-I complex which has crystallographic inversion symmetry. Each Ag atom is three- coordinated by two N atoms from two 2- aminopyridine ligands and by one O atom from a biphenyl-4,4'- dicarboxylate ligand, giving a Y- shaped coordination environment. Two Ag I atoms are linked through a biphenyl-4,4'- dicarboxylate ligand, acting as a bridge, forming a dimeric complex. The separation between the two silver( I) centres is 15.879 ( 3) Angstrom. In the crystal structure, molecules are connected by N - H ... O hydrogen bonds, forming molecular tapes in the a- axis direction.
