Abstract: The erbium nitrate complex with 6,6'-bis(diphenylphosphine oxide methyl)-2,2'-bipyridine-1,1'-dioxide was synthesized and characterized by IRspectra and molar conductance.The crystal and molecular structures of the complex were determined by single crystal X-ray diffraction technique with a four circle diffractometer to give final R and Rw values of 0.0541 and 0.0490.The crystal of the complex is monoclinic with a space group C2/c.The unit cell parameters are:α=1.9830(4)nm,b=2.3135(4)nm,c=1. 8600(3)nm;β=96.18(2)°,z=4,V=8.484(3)nm3,Dc=1.33g/cm3. The Er3+ ion is chelated by four P=Oand four N-O groups from the two organic ligands. All the coordinated water molecules are replaced by the organic ligands.
