Abstract
Abstract Three new silver(I) coordination compounds based on 2-ethyl-3-methylpyrazine (epyz), [Ag2(epyz)(pta] (1), [Ag4(epyz)2(ipa)2] (2) and [Ag8(epyz)4(npa)4] (3, H2pta = o-phthalic acid, H2ipa = m-phthalic acid, H2npa = 1,4-napthalenedicarboxylic acid), have been synthesized and have been characterized by elemental analyses, IR spectra and single-crystal X-ray diffraction. Complex 1 shows a two-dimensional network comprising Ag2 units linked by the organic ligands. In complex 2, tetrahedral Ag4 units are bridged by the organic linkers into a double-layer structure. In complex 3, the chains with alternating Ag3 and Ag5 units are connected by the organic ligands into a three-dimensional framework. The structural diversity of these compounds and the Ag units is highly dependent on different carboxylates and the coordination modes of the epyz ligand. The thermal stabilities and photoluminescence behaviors of these complexes were also discussed.
