Polymeric anhydrous sodium 2-aminobenzensulfonate
MetadataShow full item record
The crystal structure of anhydrous sodium 2-aminobenzenesulfonate, [Na(C6H6NO3S)]n, reveals the presence of a two-dimensional sandwich polymer structure based on a distorted octahedral six-coordinate NaO5N repeating unit. O-Donor atoms are from five different sulfonate groups [Na-O = 2.294 (3)-2.532 (3) ŝ and an amine nitrogen [Na-N = 2.572 (3) ŝ, completing a six-membered chelate ring including Na. Hydrogen bonds also stabilize the core structure. The outer layers of the sandwich comprise the unassociated benzene rings.
