Abstract

Five novel silver (Ι) complexes with 1,3-imidazolidine-2-thione ligand formulated as [Ag 2(η 1-SC 3H 6N 2) 6]SO 4 ( 1), [Ag 2(μ 2-SC 3H 6N 2) 2(η 1-SC 3H 6N 2) 4](NO 3) 2 ( 2), [Ag(μ 2-SC 3H 6N 2)Br] n ( 3), [Ag 2(μ 2-SC 3H 6N 2) 3(CH 3COO) 2] n ( 4), [Ag(μ 2-SC 3H 6N 2)Cl] n ( 5) have been synthesized under similar conditions except for different anions and solvents. They are structurally characterized by elemental analysis, IR, TG and single crystal X-ray diffraction. Complex 1 is a binuclear complex, with SO 4 2− anions as the counteranions. Complex 2 is a molecular binuclear silver cluster, with NO 3 − anions as the counteranions. Complex 3 shows a novel 2D lamella structure constructed by the S atom of 1,3-imidazolidine-2-thione ligand and Br − anions, and exhibits 12-membered metallacyclic rings in its structure. Complex 4 is a novel 2D layered polymer with a graphite-like array of silver (I) ions, with CH 3COO − anion coordinated to silver(I) ions by O atom. Complex 5 shows a 3D diamond-like network structure constructed by the sulfur atom of 1,3-imidazolidine-2-thione ligand and Cl − anions.
