Transition and Non-Transition Metal Complexes with 1-Formylferrocene 4-Methoxybenzoylhydrazone and 1-Acetylferrocene 4-Methoxybenzoylhydrazone

Abstract

Keactions of 1-formylfermcene 4-methoxybenzoylhydrazone (HFfmbh) and 1-acetylfermcene 4-methoxybenzoylhydrazone (HAfmbh) with hydrated metal salts yield complexes of the type [CO(L)₂ZH₂O] and [M(L)₂] (whem, M = Ni(II), Cu(II), Zn(II) or Cd(II) and HL = HFfmbh or HAfmbh). HFfmbh and HAfmbh reacted with (π-C₅H₅) Ticl_2′ Me₂SnCl₂ and MeSnCl₃ leading to the formation of the complexes (π-C552 H), Ti(Ffmbh)₂C1. (n-C₅H₅)₂ Ti(Afmbh)₂C1, Me₂ Sn(Ffmbh)₂, Me_zSn(Afmbh)₂, MeSn(Ffmbh)₂C1 and MeSn(Afmbh)₂C1. Keactions of MeSn(Ffmbh)₂C1, synthesized in this study, with MeSH, Me₃Si(NMe₂), Me₃Si(N₃) and Me₃Si-C °C-Ph afforded MeSn(Ffmbh)₂L¹ (where L¹ = SMe, NMe₂, N₃ and C Z C-Ph). 'The complexes have been characterized on the basis of elemental analyses, magnetic moment, molar conductance, molecular weight and spectmscopic (electmnic, IR and ¹H NMH) data. Both ligands function in a monobasic bidentate fashion in the complexes and the deprotonated enolic form of the ligand is involved in the coordination to the metal.
