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.
