Abstract

Silver complexes with proteinogenic amino acid ligands are of interest for biomedical and antimicrobial applications. In this work, we obtained {[Ag₇(l-his)₄](NO₃)₃·3H₂O}_0.2{[Ag₈(l-his)₄(H₂O)₂](NO₃)₄·3H₂O}_0.8(1) and {[Ag₇(d-his)₄](NO₃)₃·3H₂O}_0.2{[Ag₈(d-his)₄(H₂O)₂](NO₃)₄·3H₂O}_0.8(2), which represent the first example of any Ag-exclusive complex featuring a cluster-type core motif and with only proteinogenic amino acid ligands. Upon immersion into acetonitrile, an interesting single-crystal-to-single-crystal transformation occurred to produce a new cluster complex of the formula [Ag₈(l-his)₄(NO₃)(H₂O)](NO₃)₃(3). Using a racemic mixture of histidine, the reaction under otherwise identical conditions led to the production of the second example of a three-dimensional (3D) network structured Ag-exclusive complex with only a proteinogenic amino acid ligand. Compared with other Ag-histidine complexes in the literature, the significance of reaction conditions, particularly the Ag/histidine ratio and pH of the reaction mixture, is revealed. Temperature-dependent emission of 1 and 2 at 440 nm characteristic of silver-philophilic interactions was also observed.
