2-Amino-5-chloro-pyridinium cis-diaqua-dioxalatochromate(III) sesquihydrate.
In the crystal structure of the title compound, (C(5)H(6)ClN(2))[Cr(C(2)O(4))(2)(H(2)O)(2)]·1.5H(2)O, the Cr(III) atom adopts a distorted octa-hedral geometry being coordinated by two O atoms of two cis water mol-ecules and four O atoms from two chelating oxalate dianions. The cis-diaqua-dioxalatochromate(III) anions, 2-amino-5-chloro-pyridinium cations and uncoordinated water mol-ecules are linked into a three-dimensional supra-molecular array by O-H⋯O and N-H⋯O hydrogen-bonding inter-actions. One of the two independent lattice water molecules is situated on a twofold rotation axis.
