a.new neutra. terna.y sa.a.ium complex Sm（Phen）HL3 in which Phen is 1,10-phena.throline a.d HL is （1,3-bis（1,3-dimethyl-1H-pyra.ol-4-yl）-1,3-propa.edione） wa. synthesized. Molecula. structure of this complex wa. determined by X-ra. diffra.tion. Under UV-light this complex is demonstra.ed bright red luminescence （λma.=647 nm）, which wa. corresponding to the electric dipole 4G5/2→6H9/2 tra.sition in Sm3＋ ion. UV-a.sorption, excita.ion a.d emission spectra.of the title compound were investiga.ed.
