摘要：
The title compound, (C5H6N)[Cr(C2O4)(2)(H2O)(2)], contains one protonated pyridine molecule and one [Cr(C2O4)(2-)(H2O)(2)]-complex anion in the asymmetric unit. The Cr-III in the complex anion is coordinated in a distorted octahedral environment by two O atoms from two cis water molecules and four O atoms from two chelating oxalate dianions. The crystal packing is stabilized by intermolecular N-H center dot center dot center dot O (oxalate) and O-H center dot center dot center dot O(oxalate) hydrogen bonds and by pi-pi stacking interactions (centroid-centroid distance = 3.602 angstrom) between pyridine rings, thereby building up a three-dimensional network.
