A new Nd ( Ⅲ ) complex, Nd (Phen)2 (NO3)3 (Phen = 1,10-phenanthroline) was synthesized, and its crystal structure was determined by single crystal X-ray diffraction. Nd(Phen)2(NO3)3(Mr= 690. 68) belongs to monoclinic crystal system, space group is Cc with crystal cell parameters: a = 1.197 5 (17) nm, b = 1. 807 3 (3)nm,c=1. 309 5(2) nm,β=100. 584(3)°,V=2. 605 1(7) nm3,Z=4,Dc=1. 761 g/cm3,F(000)=1 364,μ=2. 060mm-1,λ(MoKa)=0. 071 073 nm,R=0.018 7 and wR=0.030 0 for 5 291 observed reflections with I＞2σ(I). The Nd (Ⅲ) ion is coordinated in a distorted bicapped square-antiprism geometry and surrounded by four nitrogen atoms from two phen ligands and six oxygen atoms from three NO3- anions,respectively. The Nd-N bond lengths are in the range of 0. 258 4(4) nm to 0. 265 2 nm and the Nd-O bond lengths range from 0. 249 6(3)nm to 0. 260 3 nm. The compound is characterized by IR,elemental analysis.
