New organotin complexes with trans(cis)-1,4-cyclohexanedicarboxylic acid: Synthesis, characterization and crystal structures of mononuclears, 2D network polymers and a tetratin macrocycle

Abstract: A series of new organotin carboxylates have been synthesized by reactions of trans(cis)-1,4-cyclohexanedicarboxylic acid with triorganotin chloride and diorganotin dichloride. All the complexes were characterized by elemental analysis, IR, 1H NMR, 13C NMR, 119Sn NMR spectroscopy; furthermore, complexes 1, 3, 5, 8 and 9 were characterized by X-ray diffraction analyses. The structural analyses show that complex 1 possesses a monomer structure; complex 5 possesses a 1D zigzag chain structure; both the complexes 3 and 8 have 2D network structures and complex 9 has a tetratin 36-membered macrocyclic structure.
