Synthesis and Crystal Structure of a Overall Covalent 3-D Carboxylate-bridged Silver(I) Polymer [Ag₂(bea)]_n [H₂bea = (carboxymethyl-amino) –acetic acid]

A polymeric silver(I) complex of (carboxymethyl-amino)–acetic acid (H₂bea) has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction, which features a very interesting structure. The complex crystallizes in the orthorhombic crystal system, space group Pbca, with cell constants a = 7.050(3) Å, b = 9.649(7) Å, c = 19.65(2) Å, Z = 4. The structure was solved and refined to R = 0.0599 (wR = 0.1710). In the structure of this polymer, there are mikro-carboxylate-bridged Ag(I) dimeric structural subunits, which are interlinked by bea2- ligands and the interaction between adjacent silver ions into an overall covalent three-dimensional framework.
