The title compound, [Mn(4,4'-bpy)1.5(H2O)3](ClO4)·(4,4'-bpy)(L)·H2O(1), where L=2,4,6-trimethylbenzoic acid, was synthesized and its crystal structure was determined by X-ray diffraction analysis. The crystal is of triclinic, space group P1 with a=2.929 9(6) nm, b=1.036 4(2) nm, c=8.222 0(1) nm, α=105.300(2)°, β=97.495(2)°, γ=91.118(2)°, V=1.884 0(4) nm3, Z=2, Mr=780.10, Dc=1.375 g·cm-3, μ=0.483 mm-1, F(000)=812, R=0.055 4, wR=0.135 2. The Mn atoms are octahedrally coordinated by three N atoms of three 4,4'-bipyridine ligands and three O atoms of water. The complex shows a one-dimensional chain structure bridged by water and 4,4'-bipyridine molecules. CCDC: 615707.  相似文献

Introduction Flavonoids exist widely in edible plants, and have pharmacological activity. They played a major role in the successful medical treatments at ancient times, and their uses have been persevered up to now.1-3 Flavonoid sulfates were found in a large number of plant species. They occupy an important position in the field of natu-ral products chemistry since they provide structures consisted of organic and inorganic components. The pharmacological assay revealed that flavonoid sulfat…  相似文献

Two-dimensional 4,4-bipyridyllead halides, Pbl2 (4,4‘-bpy) (1) and PbBr2 ( 4,4‘-bpy ) (2), were synthesized. The structures were determined by means of X-ray single crystal diffraction. The structure shows a distorted octahedral configuration with six-coordinated central lead atoms. In crystals 1 and 2, the molecules are packed in a two-dimensional network structure through bridging halide atoms and 4,4‘-bipyridine ligands between the adjacent lead atoms.  相似文献
