| Abstract: | Ferrous glycinate was synthesized from the raw materials glycine and iron vitriol. The crystal of ferrous glycinate was acquired by using solvent evaporation method. The crystal structure of ferrous glycinate was determined through infrared spectrogram and single- crystal X- ray diffraction analysis. The compound belonged to triclinic system,its space group was P- 1,and its lattice parameters were as follows： a = 0. 59949（ 3） nm,b = 0. 67626（ 4） nm,c = 1. 33192（ 6） nm,α = 85. 453（ 4） °,β = 82. 914（ 4） °,γ =83.115（ 5） °,V =0.53085（ 5） nm3,C4H30N2O22Fe2S2,Mr =634. 12,Z =1,R1= 0. 0219,wR2= 0. 0640 I 2σ（ I） ],S =1.005. The coordination number of iron（ Ⅱ） in this compound was six,and the coordination polyhedron was a distortionof octahedral cube configuration,the molecular formula is . |
