Abstract: The ligand 1,4,7,100-tetraazacyclodoecane-1,4,7,10-tetrakis(methylenephosphonic acid),abbreviated to H8DOTP,was synthesized and its crystal structure was determined by X-ray diffraction method.The crystal is monoclinic with space group P2/a.The cell parameters are a=1.8113(4) nm,b=1.4452(3) nm,c=1.8215(4)nm,β=97.64(3)°,V=4.7660(18) nm3,Z=4,Dc=1.528g/cm3.The final Ris 0.078,Rw=0.083.And H8DOTP complex with erbium was synthesized in aqueous solution.

Key words: Tetraazacyclododecane tetrakis(methylenephosphonic acid), Crystal structure, Erbium complex
