Abstract
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.
