Abstract

A series of novel triorganotin(IV) complexes of the type [(R~3~Sn)~3~(TMA)]·Y·L [R = CH~3~, Y = 3CH~3~OH (1); R = CH~3~, Y = 2CH~3~OH (2); R = C~6~H~5~CH~2~ (3); R = o‐F‐C~6~H~4~CH~2~ (4); R = o‐Cl‐C~6~H~4~CH~2~ (5); R = C~6~H~5~, L = CH~2~Cl~2~ (6); R = C~6~H~5~, L = EtOH·2H~2~O (7); R = C~6~H~5~, L = Et~2~O·CH~2~Cl~2~ (8); H~3~TMA = 1,3,5‐benzenetricarboxylic acid] and [(CH~3~)~3~Sn]~2~(HTMA)·H~2~O (9) have been synthesized. All complexes were characterized by elemental analysis and by IR, ^1^H, ^13^C, and ^119^Sn NMR spectroscopy. Except for 4 and 5, all complexes were also characterized by X‐ray crystallography. Complex 1 possesses a network structure where TMA acts as a tridentate ligand coordinated to three trimethyltin(IV) moieties and three methanol molecules that are involved in a hydrogen‐bond system, whereas 2 possesses a helical structure where TMA acts as a tetradentate ligand coordinated to three trimethyltin(IV) ions and two methanol molecules that bend into the helical turn in the intra‐helix hydrogen‐bond system. Complexes 3–8 are monomeric structures where TMA acts as a hexadentate ligand coordinated to triorganotin(IV) ions and 9 possesses a network structure where TMA acts as a tetradentate ligand coordinated to trimethyltin(IV) ions and water molecules in the hydrogen‐bond system that links the neighboring layers into a 3D network.
