Two novel dinuclear complexes of antimony (Ⅲ)with amino acids had been synthesized by solid-solid phase reaction at room temperature.The compositions and structures of the obtained complexes had been characterized by elemental analyses,far-infrared spectra,TG-DTA and X-ray powder diffraction.The two complexes have the compositions of Sb 2(NH 2CH 2COO) 5Cl·2 5H 2O(A),Sb 2(C 6H 5CH 2CH(NH 2)COO) 5I·2 5H 2O(B) and the molecular formula of Sb 2C 10 H 25 O 12 5 N 5Cl,Sb 2C 45 H 55 O 12 5 N 5I respectively.Far-infrared spectra of the complexes indicate that the oxygen,nitrogen and chlorine or iodine atoms have been coordinated with trivalent antimony ion.The coordination numbers of antimony ion in the complexes are six.The thermal decomposition processes of the complexes show that the final residues are antimony.The results of indexes to the X-ray powder diffraction data indicate that the crystal structure of the two complexes belong to monoclinic system.The lattice parameters are: a=0.652 6 nm, b=1.222 7 nm, c=1.387 7 nm 3, β=97 88°,V=1.096 8 nm 3 for A; a=1.061 7 nm, b=0.783 9 nm, c= 1.572 5 nm, β= 92 32°, V=1 307 7 nm 3 for B respectively.
