Four triorganotin(IV) complexes with 2‐mercaptopyrimidine (HSpym) and 4‐amino‐2‐mercaptopyrimidine (HSapym) of the type, R 3 SnL (L= Spym, R=Ph, 1; R=PhCH 2 , 2; L=Sapym, R=Ph, 3; R=PhCH 2 , 4), were synthesized. All the complexes 1–4 have been characterized by elemental, IR, 1 H NMR, and X‐ray crystallography diffraction analyses, which revealed that the structures of 1–4 are penta‐coordinated with R 3 Sn‐coordinated to the thiol S and heterocyclic N atoms, and the structural distortion for each is a displacement from tetragonal toward trigonal bipyramidal geometry. The complex 1 is a one‐dimensional chain complex, while compounds 3 and 4 are dimers due to the existence of N···H hydrogen bonding. © 2005 Wiley Periodicals, Inc.
