合成了1个锰(Ⅱ)-亚氨基二乙酸配位聚合物{Mn[(CH2COO)NH(CH2COOH)]2(H2O)2}n(1),通过X-射线衍射解析其晶体结构.该配合物属四方晶系,P 4ˉ21c空间群.晶胞参数a=0.809 7(3)nm,b=0.810 6(3)nm,c=0.953 2(3)nm;α=β=γ=90°.每个Mn(Ⅱ)离子与4个羧酸根上的氧原子和2个水分子的氧原子配位构成八面体构型,通过亚氨基二乙酸桥联成2维结构.配合物1的磁性研究表明它是一种很好的磁制冷材料. A Mn (Ⅱ) -iminodiacetic acid coordination polymer {Mn [(CH2COO) NH (CH2COOH)] 2 (H2O) 2} n (1) was synthesized and its crystal structure was analyzed by X-ray diffraction. The complex belongs to the tetragonal system, P 4 ˉ 21c space group. The unit cell parameters are a = 0.809 7 (3) nm, b = 0.810 6 (3) nm, c = 0.953 2 . Each Mn (Ⅱ) ion coordinated with the oxygen atoms of the four carboxylates and the oxygen atoms of the two water molecules to form an octahedron structure, which was bridged into a two-dimensional structure by iminodiacetic acid. The magnetic Research shows it is a good magnetic refrigeration material.
