Abstract: Six rare earth nitrate complexes of 2, 6-diacetylpyridinebis (semicarbazone) (DAPSC) were synthesized and characterized by elemental analysis, IR spectra and electrical conductance. Molecular and crystal structures of complex [Sm(DAPSC)(NO3)2(EtOH)]NO3 were determined by X-ray diffraction method. C13H21N10O12 Sm crystallized in the monoclinic apace group C2/c with the following unit-cell constants, a=16.674(2)Å, b = 10. 715(2)Å, c = 25.242(4)Å . β = 100.077(11)°; z=8, the final R factor is 0.025. The coordination number of Sm3+ is ten.
