本文合成了标题配合物,对其红外光谱进行了研究.测定了配合物的晶体结构,结果表明,晶体属三斜晶系,P1空间群,单胞参数:α=11.549(2)(?),b=14.122(3)(?),c=15.654(?),α=97.01(2)°,β=102.70(2)°,γ=105.43(2)°,V=2355.94(0.87)(?)~3,Z=2.晶体结构是采用Patterson法和差值Fourier合成解出.经全矩阵最小二乘法修正,最后偏差因子R=0.0337,R_w=0.0364.晶体中甘氨酸与Sm原子的结合方式有三种:第一种甘氨酸的羧基离子以螯合桥式与Sm原子配位;第二种甘氨酸以羧基桥式与同一单元的两个Sm原子配位;第三种甘氨酸以酸基桥式连结两个相邻单元中的相邻Sm原子而形成一维无限长链结构.此外,每个Sm原子还与两个水分子成键,其配位数为9.
In this paper, the title complex was synthesized and its IR spectra were studied. The crystal structure of the complex was determined. The results show that the crystal belongs to the triclinic system, space group P1, unit cell parameter α = 11.549 (2) a = 97.01 (2) °, β = 102.70 (2) °, γ = 105.43 (2) °, V = 2355.94 (0.87) ) ~ 3 and Z = 2. The crystal structure was solved by the method of Patterson method and the difference Fourier method, and the final deviation factor R = 0.0337 and R_w = 0.0364 by the full matrix least squares method. The binding mode of glycine and Sm atom in crystal There are three kinds: the first glycine carboxyl ion chelate bridge with the Sm atom coordination; the second glycine carboxyl bridge with the same unit of the two Sm atoms coordinate; the third glycine acid-bridged Two neighboring units in the adjacent Sm atoms form a one-dimensional infinite chain structure. In addition, each Sm atom also with two water molecules bonding, the coordination number of 9.
