Abstract :

A novel Eu(III) complex, [Eu(L)2(H2O)4].(NO3)·(H2O)4 (1) (H2L = 4-imidazolecarboxaldehyde-pyridine-2-carbohydrazide), was synthesized. Its structure has been characterized by elemental analysis, IR, and X-ray single crystal diffraction analysis. Complex 1 is of orthorhombic, space group Fdd2 with a = 29.471(6) Å, b = 10.287(2) Å, c = 24.340(5) Å, V = 7379(3) Å3, Z = 8, Mr = 902.58, Dc = 1.625 μg·m-3, μ = 1.789 mm-1, F(000) = 3656, GOOF = 1.099, the final R = 0.0517, ω R = 0.1292 for 3043 observed reflections with I > 2δ(I). The A3 coupling reaction has been investigated using the complex 1 as cata-lyst. The luminescent spectrum of the complex 1 gives two weak peaks (448 nm and 491 nm) and two strong peaks (596 nm and 620 nm) from excitation at 279 nm. Copyright © 2017 BCREC Group.
