Abstract: A 2D coordination polymer, [Ag2(HL)(MeCN)]n(H3L=2-hydroxy-3-carboxy-5-bromobenzenesulfonic acid, has been synthesized and characterized by elemental analysis, IR, TG, PL, powder and X-ray single crystal diffraction. The title complex crystallized in triclinic with space group P1, a=0.702 71(14) nm, b=0.828 98(17) nm, c=1.233 1(3) nm, α=84.32(3)°, β=73.90(3)°, γ=67.26(3)° and V=0.636 5(2) nm3, Z=2, R=0.056 5. Ag1 ion is five-coordinated by four oxygen atoms from three different HL2- groups and one coordinated acetonitrile molecule to complete a distorted square-pyramidal geometry, while Ag2 ion exists in a distorted octahedron defined by six oxygen atoms from four different HL2- groups. The oxygen atoms from sulfonate and hydroxyl groups link adjacent Ag(Ⅰ) ions to form 1D chains, which are further linked into 2D layer through carboxyl groups. In addition, this complex exhibits strong blue emission at room temperature. CCDC: 832874. |
