Abstract: The title compound, [Ag₄(C₈H₄O₄)₂{H₂N(CH₂)₆}₃]·2H₂O, is an Ag^I tetranuclear complex. Four Ag^I atoms, three hexamethylenediamine molecules, and two terephthalate dianions constitute a chain-like tetranuclear silver(I) complex. The complex lies on a center of symmetry, located at the mid-point of the central C-C bond. The two different kinds of Ag^I atoms are both in a linear environment. One kind of Ag atom is coordinated by two N atoms from different amine ligands, and the other is coordinated by an O atom from a carboxylate group and by a N atom from an amine ligand. Adjacent complexes are joined together by weak AgAg interactions to form ladder-like ribbons, which are further linked by hydrogen bonds to form a three-dimensional structure.
