Abstract
In the title complex, [Ag(C7H10N2O2S)2]NO3, the AgI cation is bicoordinated in an almost linear configuration by two N-donor atoms of the thiazole rings of two distinct ethyl 2-amino-4-thiazoleacetate (EATA) ligands. The dihedral angle between the two thiazole rings is 49.9°. A weak Ag⋯O (2.729 Å) interaction between the Ag cation and one of the O atoms from the nitrate anion is observed, and a pseudo-dimer is formed through a weak Ag⋯S (3.490 Å) interaction between the Ag cation and the S atom of the thiazole ring of a symmetry-related molecule. In the crystal structure, there are intra- and intermolecular N—H⋯O hydrogen bonds. The occurrence of intermolecular N—H⋯O hydrogen bonds results in the formation of two-dimensional sheets parallel to (010), which are further linked into a three-dimensional network through weak C—H⋯O interactions.
