| Abstract: | Three Ag(I) complexes of reduced Schiff base amino acid ligands, [Ag2(Hshis)2]·3H2O (1), Ag(Hcgly) (2), and Ag(cala) (3) (H2shis = N-(2-hydroxybenzyl)-l-histidine, H2cgly = N-(2-hydroxy-5-chlorobenzyl)-glycine, Hcala = N-(4-chlorobenzyl)-d,l-alanine), have been synthesized and characterized by X-ray crystallography. Complex 1 shows a dimeric structure, while complex 2 shows one-dimensional zigzag chains, which are extended into a two-dimensional supramolecular sheet by hydrogen bonds. Complex 3 exhibits a 2D sheet structure with dangling arms. The antimicrobial activities of the complexes have been investigated. |
