Abstract

The synthesis and characterization of zinc complexes bearing an amidodiamine ligand, (EtO)₄Zn₃[N(CH₂CH ₂NMe₂)₂]₂ (1), [(Et ₃CO)ZnN(CH₂CH₂NMe₂) ₂]₂ (2) and [(2,6-ⁱPr₂C ₆H₃O)ZnN(CH₂CH₂NMe₂) ₂]₂ (3), [(Me₃Si)₂N]Zn[N(CH ₂CH₂NMe₂)₂] (4) and [(Me ₃Si)₂N]₂Zn₂(OH)[N(CH ₂CH₂NMe₂)₂] (5), are reported. Compounds 1-3 are synthesised in the reactions of {Zn[N(CH₂CH ₂NMe₂)₂]₂}₂ with 2 equiv. of ethanol, 3-ethyl-3-pentanol and 2,6-diisopropylphenol, respectively. Compound 4 is obtained by the reaction of Zn[N(SiMe₃) ₂]₂ with HN(CH₂CH₂NMe ₂)₂, and compound 5 is synthesised by reacting 4 with 1 equiv. of H₂O. Compound 4 is characterized by NMR and MS while all of the other compounds are characterized with NMR, MS, elemental analysis and single-crystal X-ray diffraction. Compound 1 is a trinuclear species containing a Zn₃N₂O₂ core. Compounds 2 and 3 are dimeric with planar Zn₂N₂ rings. Compound 5 is dimeric with a planar Zn₂NO ring.
