摘要
Five novel silver (I) complexes with 1,3-imidazolidine-2-thione ligand formulated as [Ag-2(eta(1)-SC3H6N2) (6)]SO4 (1), [Ag-2(mu(2)-SC3H6N2)(2)(eta(1)-SC3H6N2)(4)](NO3)(2) (2), [Ag(mu(2)-SC3H6N2)Br](n) (3), [Ag-2(mu(2)-SC3H6N2) (3)(CH3COO)(2)](n) (4), [Ag(mu(2)-SC3H6N2)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 SO42- anions as the counteranions. Complex 2 is a molecular binuclear silver cluster, with NO3 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 CH3COO- 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. (c) 2009 Elsevier B.V. All rights reserved.
