A new neutral ternary samarium complex Sm(Phen)HL3 in which Phen is 1,10-phenanthroline and HL is (1,3-bis(1,3-dimethyl1H-pyrazol-4-yl)-1,3-propanedione) was synthesized.Molecular structure of this complex was determined by X-ray diffraction.Under UV-light this complex is demonstrated bright red luminescence (λmax=647 nm),which was corresponding to the electric dipole 4G5/2→,6H9/2 transition in Sm3+ ion.UV-absorption,excitation and emission spectra of the title compound were investigated.
