【 摘 要 】

The asymmetric unit of the title compound, Ag[Cr(C11H14N2O8)]·3H2O, contains one [Cr(1,3-pdta)]− anion [1,3-pdta is (propane-1,3-diyldi­nitrilo)­tetra­acetate], one Ag+ cation and three water mol­ecules. The Cr3+ ion is coordinated to the four O and two N atoms of the 1,3-pdta ligand, displaying a distorted octa­hedral geometry. The mean Cr—N and Cr—O bond lengths are 2.0727 (17) and 1.9608 (15) Å, respectively. The conformations of the chelate rings were found to be envelope for the glycinates and twist-boat for the six-membered di­amine (T) ring. The Ag+ cation is surrounded by six O atoms from three non-coordinated carbonyl O atoms of neighbouring 1,3-pdta groups and three water mol­ecules. The crystal structure is stabilized by inter­molecular hydrogen bonding involving the water O—H group as donor and the carboxyl O atom as acceptor.
