摘要: 用2-氨基-5-巯基-1,3,4-噻二唑乙酸(Hatma)为配体合成出2种新型同构的稀土配合物[Ln(atma)₃(H₂O)₂]_n(Ln=La(1),Nd(2))。配体和2个配合物的结构均由X-射线单晶衍射法确定,同时对配合物进行了IR,TGA及元素分析。单晶结构表明,配体属单斜晶系,C2/c空间群,晶胞参数为a=2.1419(9)nm,b=0.40076(17)nm,c=1.7500(8)nm,V=1.4950(11)nm³,Z=4;配合物1和2的晶体都属于三斜晶系,空间群为P1,配合物1的晶胞参数为a=0.8820(3)nm,b=1.2306(4)nm,c=1.2586(4)nm,V=1.2913(7)nm³,Z=2;配合物2的晶胞参数为a=0.8834(4)nm,b=1.2283(5)nm,c=1.2510(5)nm,V=1.2821(9)nm³,Z=2。2个配合物均形成一维链状空间结构,通过丰富的氢键连接形成三维超分子结构。抗菌试验表明,配合物比配体表现出更好的生物活性。初步的植物生长实验表明,配合物对油菜和小麦的生长具有一定的促进作用。

Abstract: Two lanthanide(Ⅲ) complexes, [Ln(atma)₃(H₂O)₂]_n have been synthesized (Ln=La (1) and Nd (2);Hatma=[5-amino-1,3,4-thiadiazol-2-yl]thioglycolic acid). The structure of Hatma ligand and complexes 1, 2 have been determined by X-ray structural analysis and the structure parameters were analyzed as follows: Hatma, monoclinic, C2/c, a=2.1419(9) nm, b=0.40076(17) nm, c=1.7500(8) nm, V=1.4950(11) nm³, Z=4;1, triclinic, P1, a=0.8820(3) nm, b=1.2306(4) nm, c=1.2586(4) nm, V=1.2913(7) nm³, Z=2;2, triclinic, P1, a=0.8834(4) nm, b=1.2283(5) nm, c=1.2510(5) nm, V=1.2821(9) nm³, Z=2. These two complexes are isomorphic and have one-dimensional chain and rich hydrogen bonds which result in three-dimensional supramolecular structures. The complexes were determined by IR, TGA, elemental analysis and single crystal X-ray diffraction. The antimicrobial assays indicate that the two complexes show better activities than free ligand Hatma. The promoting effects of the title complexes on rape and wheat growth were also tested preliminarily. CCDC: 902095, Hatma;830535, 1;830536, 2.
