Pyridinium cis-diaqua-bis-(oxalato-κ(2)O,O')chromate(III).

Bottom Line: The title compound, (C(5)H(6)N)[Cr(C(2)O(4))(2)(H(2)O)(2)], contains one protonated pyridine mol-ecule and one [Cr(C(2)O(4))(2)(H(2)O)(2)](-) complex anion in the asymmetric unit.The Cr(III) in the complex anion is coordinated in a distorted octa-hedral environment by two O atoms from two cis water mol-ecules and four O atoms from two chelating oxalate dianions.The crystal packing is stabilized by inter-molecular N-H⋯O(oxalate) and O-H⋯O(oxalate) hydrogen bonds and by π-π stacking inter-actions (centroid-centroid distance = 3.602 Å) between pyridine rings, thereby building up a three-dimensional network.

ABSTRACT
The title compound, (C(5)H(6)N)[Cr(C(2)O(4))(2)(H(2)O)(2)], contains one protonated pyridine mol-ecule and one [Cr(C(2)O(4))(2)(H(2)O)(2)](-) complex anion in the asymmetric unit. The Cr(III) in the complex anion is coordinated in a distorted octa-hedral environment by two O atoms from two cis water mol-ecules and four O atoms from two chelating oxalate dianions. The crystal packing is stabilized by inter-molecular N-H⋯O(oxalate) and O-H⋯O(oxalate) hydrogen bonds and by π-π stacking inter-actions (centroid-centroid distance = 3.602 Å) between pyridine rings, thereby building up a three-dimensional network.
