A novel one-dimensional silver cylinder stabilized by mixed 2-mercaptobenzoic acid and ethylene­diamine ligands

A novel infinite one-dimensional silver cylinder, namely poly[[mu]-ethyl­enedi­am­ine-[mu]₅-(2-sulfanidylbenzoato)-[mu]₄-(2-sul­fanidylbenzoato)-tetra­silver(I)], [Ag₄(C₇H₄O₂S)₂(C₂H₈N₂)]_n, has been synthesized by one-pot reaction of equivalent molar silver nitrate and 2-mercaptobenzoic acid (H₂mba) in the presence of ethyl­enediamine (eda). One Ag atom is located in an AgS₂NO four-coordinated tetra­hedral geometry, two other Ag atoms are in an AgS₂O three-coordinated T-shaped geometry and the fourth Ag atom is in an AgSNO coordination environment. The two mba ligands show two different binding modes. The [mu]₂-N:N'-eda ligand, acting as a bridge, combines with mba ligands to extend the Ag^I ions into a one-dimensional silver cylinder incorporating abundant Ag...Ag inter­actions ranging from 2.9298 (11) to 3.2165 (13) Å. Inter­chain N-H...O hydrogen bonds extend the one-dimensional cylinder into an undulating two-dimensional sheet, which is further packed into a three-dimensional supra­molecular framework by van der Waals inter­actions; no [pi]-[pi] inter­actions were observed in the crystal structure.
