甘氨酸锰的合成及表征
The Synthesis and Characterization of Glycine Manganese

以甘氨酸和硫酸锰为原料合成了饲料添加剂甘氨酸锰，并通过IR、TG和X-射线单晶衍射分析确定了化合物的结构.分析表明甘氨酸锰为复合物，其晶体属于三斜晶系，空间群为 P-1，晶胞参数：a=0.60244（3）nm，b=0.67869（4）nm，c =1.39110（8）nm，α=85.447（5）°，β=83.221（5）°，γ=83.229（5）°，V=0.53085（5）nm3，分子式为 C2 H15 NO11 MnS，Mr =316.15，Z =2，R1=0.0225，wR2=0.0562（I>2σ（I）），S=1.081.化合物中锰的配位数为6，配位多面体为变形的八面方体构型，分子式为｛[Mn（C2H5NO2）2SO4？4H2O]（MnSO4？6H2O）｝.
Glycine and manganese sulfate were used to synthesis manganese glycine which was a kind of feed addi-tives. Its structure was determined by IR,TG and X-ray single crystal diffraction analysis. Analysis showed that the complex crystallizes in triclinic,space group P-1,a=0. 602 44(3)nm,b=0. 678 69(4)nm,c=1. 391 10(8)nm,α=85. 447(5)°,β=83. 221(5)°,γ=83. 229(5)°,V=0. 530 85(5)nm3 ,C2 H15 NO11 MnS,Mr=316. 15,Z=2, R1 =0. 022 5,wR2 =0. 056 2(I>2σ(I)),S=1. 081. Center of complex ions of Mn coordination number is 6,coor-dination polyhedron as distortion of octahedral configurations,the molecular formula is{[Mn(C2H5NO2)2SO4？4H2O]？ (MnSO4？6H2O)}
