The asymmetric unit of the title polymeric compound, [Li2(C16H11N2O2)2(C16H12N2O2)2(CH3CH2OH)2]n, contains two LiI ions, two 3-(1-phenyl-1H-pyrazol-3-yl)benzoate ions, two 3-(1-phenyl-1H-pyrazol-3-yl)benzoic acid molecules and two ethanol molecules. In the crystal structure, each of the two LiI ions has a distorted tetrahedral geometry, coordinated by two carboxylate O atoms, one carboxyl O atom and one ethanol O atom. The carboxylate group bridges the LiI ions, forming a one-dimensional polymeric chain along [100]. The crystal structure is further stabilized by O—H...O and C—H...N hydrogen bonding, and π–π interactions with centroid–centroid distances in the range 3.6534 (13)–3.8374 (13) Å.
