摘要
采用水热法合成出一种新型二维杂金属配位聚合物[La(H ida)Co(ida)2].0.5H2O(ida=氨基二乙酸),并通过X射线单晶结构分析、红外光谱分析、元素分析、热重分析以及X射线粉末衍射分析对该化合物进行了表征.结构分析数据表明,该化合物属单斜晶系,C2/c空间群,晶胞参数a=0.970 78(19)nm,b=2.412 8(5)nm,c=0.859 64(17)nm,β=114.91(3),°V=1.826 3(6)nm3,Z=4,R=0.012 6.该化合物是由一维La-Co杂金属链通过四齿羧酸配体连接形成的新型二维杂金属配位聚合物.
A new lanthanum ( Ⅲ ) -cobalt ( Ⅱ ) heterometallic polymeric complex of La (Hida) Co (ida) 2 · 0. 5H2O( 1, ida = iminodiacetate) was hydrothermally synthesized and structurally characterized by the elemental analyses, IR spectrum and the single-crystal X-ray diffraction. The structure of compound 1 consists of one-dimensional lanthanum-cobalt heterometallic chain, which was linked via “linear” tetradentate ida ligands to form the two-dimensional framework. The crystal data for compound 1: monoclinic system, space group C2/c, α =0. 970 78(19) nm, b =2. 412 8(5) nm, c =0. 859 64(17) nm,β = 114. 91 (3)°, V= 1. 826 3 (6) nm^3, Z =4 and R =0. 012 6. Interestingly, the title compound contains ten-coordinate lanthanide( Ⅲ ) ions, which makes it unique as the heteronuclear lanthanide iminoacetate.
