The synthesis and characterization of zinc complexes bearing an amidodiamine ligand, (EtO)(4)Zn(3)[N(CH(2)CH(2)NMe(2))(2)](2) (1), [Et(3)CO)ZnN(CH(2)CH(2)NMe(2))(2)](2) (2) and [(2,6-(i)Pr(2)C(6)H(3)O)ZnN(CH(2)CH(2) NMe(2))(2)](2) (3), [(Me(3)Si)(2)N]Zn[N(CH(2)CH(2)NMe(2))(2)] (4) and [(Me(3)Si)(2)N](2)Zn(2)(OH)[N(CH(2)CH(2)NMe(2))(2)] (5), are reported. Compounds 1-3 are synthesised in the reactions of {Zn[N(CH(2)CH(2)NMe(2))(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(SiMe(3))(2)](2) with HN(CH(2)CH(2)NMe(2))(2), and compound 5 is synthesised by reacting 4 with 1 equiv. of H(2)O. 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 Zn(3)N(2)O(2) core. Compounds 2 and 3 are dimeric with planar Zn(2)N(2) rings. Compound 5 is dimeric with a planar Zn(2)NO ring. (C) 2010 Elsevier Ltd.
