In the crystal structure of imatinibium dipicrate systematic name: 1-methyl-4-(4-{4-methyl-3-4-(3-pyrid\-yl)pyrimidin-2-yl\-amino]\-anilinocarbon\-yl}benz\-yl)piperazine-1,4-diium dipicrate], C\sb 29H\sb 33N\sb 7O\sp 2+⋅2C\sb 6H\sb 2N\sb 3O\sb 7\sp -}}, the imatinibium cation is proton\-ated at both of the pyrimidine N atoms. Each of the two picrate anions inter\-acts with the diprotonated cation through bifurcated N—-H⋅sO hydrogen bonds forming \it R\sb 1\sp 2(6) ring motifs. Also, an \it R\sb 2\sp 2(24) graph set is formed between the benzamidium —NH— group and the 4-pyridyl N atom inter\-acting through N—-H⋅sN hydrogen-bond inter\-actions. Additional weak C—-H⋅s\it Cg π-ring and π—π inter\-molecular inter\-actions are observed which also influence crystal packing.
