The organotin(IV) chlorides R n SnCl 4-n (n = 3, R = Ph, PhCH 2 , n-Bu; and n = 2, R = n-Bu, Ph, PhCH 2 ) react with 4,4 -bipyridine (4 4-bpy) to give [(Ph 3 SnCl) 2 (4,4 -bpy) [(n-Bu) 3 SnCl] 2 (4,4 -bpy) (3), [(n-Bu) 2 SnCl 2 (4,4 -bpy)] ( 4), [Ph 2 SnCl 2 (4,4 -bpy)] ( 5), and [(PhCH 2 ) 2 SnCl 2

✦ Synopsis
Four organotin complexes with 2,2 -bipyridine-4,4 -dicarboxylic acid, H 2 dcbp: (dcbp)] n 4 have been synthesized. The complexes 1-4 were characterized by elemental, IR, 1 H, 13 C, 119 Sn NMR, and X-ray crystallographic analyses. Crystal structures show that complex 1 is a monomer with one ligand coordinated to two triorganotin moieties, and a 1D infinite polymeric chain generates via intermolecular C H•••N hydrogen bond; complex 2 is also a monomer and forms a 2D network by intermolecular O-H•••O weak interaction; both of complexes 3 and 4 form 2D network structures where 2,2 -bipyridine-4,4dicarboxylate acts as a tetradentate ligand coordinated to trimethyltin and tri-n-butyltin ions, respectively.
