摘要：

The asymmetric unit of the title solvated molecular salt, (C5H6N)[Cr(C2O4)(2)(H2O)(2)]center dot CO(NH2)(2), contains half a formula unit. Each component is completed by crystallographic twofold symmetry: in the cation, one C and the N atom lie on the rotation axis; in the anion, the Cr-III ion lies on the axis; in the solvent molecule, the C and the O atom lie on the axis. The aqua ligands are in a trans disposition in the resulting CrO6 octahedron. In the crystal, the components are linked by O-H center dot center dot center dot O, N-H center dot center dot center dot O and N-H center dot center dot center dot(O,O) hydrogen bonds, generating a three-dimensional network.
