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.

Three novel macrocyclic diorganotin(IV) compounds of the type: {[R10(SnO)3(SnOH)2]HnXOm}2 · L (n=1, m=4, R=PhCH2, X=P, L=0, 1; n=0, m=4, R=PhCH2, X=S, L=4H2O, 2; n=0, m=3, R=n-Bu, X=N, L=0, 3) were synthesized by the reaction of (PhCH2)2SnCl2 with Na2HnXO4 (n=1, X=P; n=0, X=S) or (n-Bu)2SnCl2 with NaNO3. All the compounds 1, 2 and 3 are characterized by elemental, IR and X-ray diffraction analyses. X-ray data reveal that a macrocyclic structure with two centrosymmetric ladders of hydrolysis exists in the crystals of the three compounds. The geometry about each tin atom involved is trigonal bipyramidal. [Copyright &y& Elsevier]
