The crystal structure of the copper(II) chloride complex of the thyroid hormone precursor, 3,5-diiodo-L-tyrosine, (C_9H_9I_2NO_3・CuCl) was determined by the X-ray diffraction method. The space group is P2_12_12_1,with cell dimensions a=8.405(2), b=20.694(3) and c=7.532(3) Å. The structure was refined to R=0.064 for 1374 reflections(I >3σ(I)). The Cu(II) ion is six-coordinated by interaction with one amino nitrogen, two carboxyl oxygens and one chlorine atom in a square plane, and the phenol iodine and oxygen atoms in axial positions. Three-dimensional arrangement of the molecules are stabilized by two hydrogen bonds of O-H(pheno)・・O(carboxyl), and N-H(amino)・・O(carboxyl).
