Self‐assembly of dibutyltin oxide with 3‐(1,3‐dioxo‐2,3‐dihydro‐1H‐phenalen‐2‐yl)benzoic acid (HL) produces ( n Bu) 2 SnL 2 ( 1 ) when benzene is used as solvent, whereas the reaction generates {[( n Bu) 2 SnO] 2 L} 2 · C 7 H 8 ( 2 ) when toluene is the reactive solvent. The novel organotin carboxylate ( n Bu) 2 SnL 2 ( 1 ) was characterized by elemental analysis, as well as IR, 1 H, 13 C, and 119 Sn NMR spectroscopy. Single crystal X‐ray study reveals that 1 is a dialkyltin carboxylate monomer possessing crystallographically imposed twofold symmetry. Ligand HL in 1 chelates with tin atom in bidentate coordination mode. The molecules of 1 build complicate 1D, 2D, and 3D structures via intermolecular hydrogen bonds, and π ··· π interactions can be found in the 3D architecture. The preliminary fluorescence activity and antitumor activity of the complex were also studied.
