Synthesis and Characterization of a Novel Coordination Complex Based on Fluorescein

novel coordination complex, {[Cd2(C20H10O5)2(H2O)4]·10H2O}n, has been synthesized based on fluorescein (2-(6-hydroxy-3-oxo-3H-xanthen-9-yl) benzoic acid) and systematically characterized by elemental analysis, infrared (IR) spectrum, thermo gravimetric analysis (TGA), powder X-ray diffraction (PXRD) and single-crystal X-ray diffraction. Compound 1 crystallizes in monoclinic, space group P2/n with a = 20.428(5), b = 8.084(2), c = 21.689(5) ?, β = 96.360(5)o, Mr = 993.46, V = 3559.7(15) ?3, Z = 4, Dx = 1.845 g/cm3, μ = 1.276 mm-1, F(000) = 1974.0, GOOF = 1.044, λ(MoKα) = 0.71073 ?, the final R = 0.0553 and wR = 0.1720 for 7245 observed reflections with I > 2σ(I).
