Redetermination of ammonium oxalate oxalic acid dihydrate

open access: yesActa Crystallographica Section E Structure Reports Online, 2006
The crystal structure of the triclinic form of the title compound, NH4+·C2HO4−·C2H2O4·2H2O, has been redetermined, providing a significant increase in the precision of the derived geometric parameters. The asymmetric unit comprises an ammonium cation, an oxalate anion, half each of two oxalic acid mol­ecules, each disposed about a centre of inversion ...
