Abstract: In the title compound [systematic name: 1,10-phenanthrolin-1-ium 4-(3-carboxy-2-hydroxynaphthylmethyl)-3-hydroxy-2-naphthoate N,N-dimethylformamide solvate], C₁₂H₉N₂⁺·C₂₃H₁₅O₆^-·C₃H₇NO, the two naphthyl ring systems of the pamoate monoanion are perpendicular to each other. O-HO, N-HO and C-HO hydrogen-bonding interactions and - stacking interactions stabilize the crystal structure.
