Three series of methoxyphenyl substituted β-diketiminate and β-enaminoketonate and chlorophenyl β-enaminoketonate ligands were prepared and studied by IR, 1H and 13C NMR spectroscopy in solution and X-ray diffraction techniques in solid state. The crystal structures of [2-(MeO)C6H4]N=(H)-CCH(H)C[2-(MeO)C 6H4]NH.HCl,[2-(MeO)C6H4]N=(H)CCH(H) C[2-(MeO)C6H4]NH, [4-(MeO)C6H 4]N=(H)CCH-(H)C[4-(MeO)C6H4]NH, [4-ClC 6H4]N(H)(Me)CCH(Me)C=O, [2-(MeO)C6H 4]N=(Me)CCH(Me)C[2-(MeO)C6H4]NH and 7-methoxy-2,4-dimethylquinoline-toluenesulfonylacid adduct as ligands, their precursors and a byproduct isolated during the synthesis of [3-(MeO)C 6H4]N(H)(Me)CCH(Me)C=O were determined. One of the ligands the meta-methoxyphenyl substituted β-enaminone has been treated with n-butyllithium to give {[3-ClC6H4]N(Me)CCH(Me)C=O}Li which reveals tetrameric structure in the solid state. Further reactions of this lithium complex with tri- and diorganotin(IV) chlorides and hydride give appropriate organotin(IV) complexes with five coordinated tin atom. The direct reaction of bis(para-methoxyphenyl) substituted β-diketimine with Sn[N(SiMe3)2]2 gives [4-(MeO)C 6H4]N=(H)CCH(H)C[4-(MeO)C6H4] NSnN(SiMe3)2. Structure of these complexes was evaluated by 1H, 7Li and 119Sn NMR spectroscopy and X-ray diffraction analysis for two examples.
