Abstract

The acyclic Schiff-base ligands (2-(OH)-5-(R3)C 6H2-1,3-(HCNC(R1)(R2)CO 2H), derived from the dialdehyde 2-hydroxy-5-R-1,3- benzenedicarboxaldehyde (R = Me or t-Bu) and two equivalents of the amino acids glycine, 2,2-diphenylglycine or phenylalanine, have been reacted with the metal acetates M(OAc)2 (M = Cu, Zn) in the presence of triethylamine, affording the complexes [HNEt3][M2(CH3CO 2)2(2-(O)-5-(t-Bu)C6H2-1,3- (HCNC(R1)(R2)CO2)2] (M = Cu, R 1 = R2 = C6H5, R3 = Me (1); M = Zn, R1 = R2 = H, R3 = t-Bu (2); M = Zn, R1 = R2 = C6H5, R3 = t-Bu (3); M = Zn, R1 = H, R2 = CH2C 6H5, R3 = t-Bu (4)) in good yields. The crystal structures of 1·MeCN, 2·112MeOH, 3·2MeOH, and 4·3MeOH have been determined. © 2010 Elsevier B.V. All rights reserved.
