Abstract: The title compound, [Sn(C₆H₅)₃(C₁₉H₁₆N₃O₃)], is a four-coordinate Sn^IV complex, with a distorted tetrahedral geometry and one disordered (0.54:0.46) phenyl ring. The Schiff base carboxylate group acts as a monodentate ligand coordinating through the deprotonated hydroxyl O atom. In the crystal structure, a weak offset face-to-face aromatic - stacking interaction can be found between the pyrazole ring and the benzene ring of 4-formylbenzoic acid. The centroid-to-centroid distance is 3.858 (2) Å and the interplanar distance is 3.375 (4) Å.
