收藏资源简介：
A novel fulvene-type bidentate ligand 1 has been synthesized by an aroylation reaction of cyclohexyl-substituted cyclopentadienyl anions. Compound 1 crystallizes in the triclinic space group P1̄, with a = 7.0419(5) Å, b = 11.9360(8) Å, c = 15.6470(11) Å, α = 85.1440(10)°, β = 78.1140(10)°, γ = 74.5360(10)°, V = 1239.76(15) Å3, and Z = 2. The coordination chemistry of 1 was investigated, and a novel Ag-containing coordination polymer (2), linked by both Ag−heteroatom and Ag−carbon interactions, has been synthesized. The coordination polymer has been fully characterized by infrared spectroscopy, elemental analysis, and single-crystal X-ray diffraction. Compound 2 crystallizes in the triclinic space group P1̄, with a = 7.1654(5) Å, b = 15.7277(11) Å, c = 18.8157(13) Å, α = 73.5150(10)°, β = 89.0410(10)°, γ = 89.0970(10)°, V = 1355.19(14) Å3, and Z = 2. The solid-state structure of 2 features a one-dimensional double-chain motif. These double chains are in turn cross-linked to each other via strong interchain O−H···O hydrogen bonds, forming a novel two-dimensional network with remarkably large cavities (effective cross section of ca. 21 × 15 Å) that are occupied by benzene guest molecules. Both compounds 1 and 2 are luminescent in the solid state, and a large blue-shift in the emission between the free ligand 1 and the ligand incorporated into complex 2 is observed.
