The Crystal Structure of a Gatifloxacin Complex and its Fluorescent Property

The hydrothermal reaction of Cd(ClO₄)₂·6H₂O and Gatifloxacin(Gati) affords a binuclear complex of Gatifloxacin, Cd(Gati)(py)₃]₂·(ClO₄)₄ ( 1 ), which is characterized by X‐ray crystallographic analysis, IR and fluorescent spectroscopy. Crystal data for 1 , C₃₄H₃₆CdCl₂FN₆O₁₂: monoclinic, P2₁/c, a = 18.3642(5), b = 12.8156(4), c = 16.7210(5) Å, β = 97.931(1)°, V = 3897.6(2) ų, Z = 4. The local surrounding of the Cd^II ion is a slightly distorted octahedron. Solid‐state fluorescence measurements of 1 at room temperature show an emission peak at 439 nm.
