摘要：

In the structure of the title compound, (C5H7N2)[Cr(C2O4)(2)(H2O)(2)], two crystallographically independent formula units are present. Both chromium atoms are six- coordinated in a distorted octahedral geometry by two chelating equatorial oxalato ligands and two axial water molecules. The [Cr(C2O4)(2)(H2O)(2)](-)anions and C5H7N2+ cations are linked through a complex three-dimensional hydrogen- bonding network consisting of N-H ... O and O-H ... O interactions.
