چکیده
In the title complex, (C(5)H(6)N)[Cr(CH(4)O(6)P(2))(2)(H(2)O)(2)]·4H(2)O, the Cr(III) atom, lying on an inversion centre, is coordinated by two bidentate methyl-ene diphospho-nate ligands and two water molecules in a distorted octa-hedral coordination geometry. The pyridinium cation is located on an inversion centre, with an N atom and a C atom sharing a position each at a half occupancy. A three-dimensional network is constructed by O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds between the pyridin-ium cation, complex anion and uncoordinated water mol-ecules.
