[Bi2Cl10(H2-Norf)4(H2O)8](H-Norf是诺氟沙星)(英)

The crystal structure of [Bi2Cl10(H2-Norf)4(H2O)8] (1) comprises [H2-Norf]^ cations and [Bi2Cl10]4^- anions, that are loosely associated via H-bonding interactions, as well as water molecules that also participate in H-bonding interactions. Strong blue-fluorescent emission of 1 at solid state is observed at the room temperature. CCDC:238237.     

Sharpless四唑合成中捕获双四唑锌配合物

The reaction of malononitrile with ZnCl₂ and NaN₃ in the presence of 2,2′-bipyridine and water affords the first bis(tetrazole) Zn-complex intermediate, mono(2,2′-bipyridine)bis(tetrazolyl)methane aqua zinc(Ⅱ), [Zn(2,2′-bpy)(BTZ)(H₂O)]·(H₂O)₂ (1) which gives a clue for Demko-Sharpless′ tetrazole synthesis. Crystal data for 1: C₁₃H₁₈N₁₀O₄Zn, M_r=443.74, monoclinic, space group P2₁/c, a=12.5705(18), b=16.078(2), c=9.1921(13)?, β=95.010(3)°, V=1850.7(5)?³, Z=4. CCDC: 197788.     

含非交换氘的四唑-锌配合物

The solvothermal reaction (D₂O) of 2,6-dideuterium-4-cyanopyridine with ZnCl₂ in the presence of NaN₃ offers a novel complex Zn(OD)(C₆H₂D₂N₄) (1) in which Zn has a distorted tetrahedron composed of two N atoms from one tetrazoyl group and pyridyl group and two O atoms from two deuteratohydroxy OD groups.
