Bottom Line: In the title hybrid salt, (C(5)H(7)N(2))[Cr(H(2)O)(2)(C(2)O(4))(2)], the Cr(III) ion is coordinated in a slightly distorted octa-hedral environment by four O atoms from two oxalate ligands in the equatorial plane and by two water O atoms in the axial sites.The 2-amino-pyridinium cation is disordered over two sets of sites in a 0.800 (7):0.200 (7) ratio.In the crystal, N-H⋯O and O-H⋯O hydrogen bonds connect the components into a three-dimensional network.

ABSTRACT
In the title hybrid salt, (C(5)H(7)N(2))[Cr(H(2)O)(2)(C(2)O(4))(2)], the Cr(III) ion is coordinated in a slightly distorted octa-hedral environment by four O atoms from two oxalate ligands in the equatorial plane and by two water O atoms in the axial sites. The 2-amino-pyridinium cation is disordered over two sets of sites in a 0.800 (7):0.200 (7) ratio. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds connect the components into a three-dimensional network. The crystal studied was an inversion twin with components in a ratio 0.75 (2):0.25 (2).
