Abstract

The title compound, 2C8H20N+ C2O4 22H2O, synthesized by neutralizing H2C2O42H2O with (C2H5)4NOH in a 1:2 molar ratio, is a deliquescent solid. The oxalate ion is nonplanar, with a dihedral angle between carboxylate groups of 64.37 (2). O—HO hydrogen bonds of moderate strength link the O atoms of the water molecules and the oxalate ions into rings parallel to the c axis. The rings exhibit the graph-set motif R4 4 (12). In addition, there are weak C—HO interactions in the crystal structure.
