The title compound, (C(4)H(8)N(3)O)[Cr(C(7)H(3)NO(4))(2)]·C(7)H(5)NO(4)·6H(2)O, was obtained by the reaction of Cr(NO(3))(3)·9H(2)O with pyridine-2,6-dicarboxylic acid (pydcH(2)) and creatinine (creat) in aqueous solution (molar ratio 1:2:2). The cation is a protonated creatinine (creatH(+)) while the anion is a bis-pydc(2-) Cr(III) complex. The Cr(III) is coordinated by four oxygen and two nitro-gen atoms of two (pydc)(2-) groups and has a disorted octa-hedral coordination environment. The structure also contains a neutral mol-ecule of pydcH(2) that is hydrogen bonded to the creatH(+) and six mol-ecules of water. Extensive inter-molecular inter-actions, including seventeen classical hydrogen bonds, two weak C-H?O bonds, and C-O?? stacking inter-actions, with O?centroid distances of 3.211?(13) and 3.300?(12)?Å, connect the various components in the crystal structure.
