Five new diorganotin N‐[(3‐methoxy‐2‐oxyphenyl)methylene] tyrosinates, R2Sn[2‐O‐3‐MeOC6H3CH=NCH (CH2C6H4OH‐4)COO] (R = Me, 1; Et, 2; Bu, 3; Cy, 4; Ph, 5), have been synthesized and characterized by elemental analysis, IR, NMR (1H, 13C and 119Sn) spectra, and the X‐ray single crystal diffraction. In non‐coordinated solvent, complexes 1–5 have penta‐coordinated tin atom. In the solid state, 1–3 are centrosymmetric dimmers in which each tin atom is seven‐coordinated in a distorted pentagonal bipyramid, and 4 displays discrete molecular structure with distorted trigonal bipyramidal geometry, and the tin atom of 5 is hexa‐coordinated and possess the distorted octahedral geometry with a coordinational methanol molecule. The intermolecular O‐H⋅⋅⋅O hydrogen bonds in 1–4 link molecules into the different one‐dimensional supramolecular chain with R22 (30) or R22 (20) macrocycles, and the molecules of 5 are joined into a two‐dimensional supramolecular network containing R44 (24) and R44 (28) two macrocycles. Bioassay results against human tumour cell HeLa indicated that 3‐5 belonged to the efficient cytostatic agents and the activity decreased in the order 4>3>5>2>1. The fluorescence determinations show the complexes may be explored for potential luminescent materials.
