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.
