摘要
以N((3-吡啶基)磺酰基)天冬氨酸(H_2L)为配体,采取水热合成的方法,合成了配位聚合物[M(HL)_2]_n(M=Co,1;Zn,2;Cd,3).X射线单晶衍射分析表明,它们的晶体同构。1的磁性分析表明,1的Curie常数为4.66 cm^3·mol^(-1)·K,Curie-Weiss常数为-21.23 K;与配体H_2L相比,2和3的发射光谱发生了明显的蓝移,可能归因于配体到金属的电荷转移。
The title coordination polymers of [M(HL)2]n (M=Co, 1; Zn, 2; Cd, 3) based on H2L (H2L=N-((3-pyridine) sulfonyl)aspartate) have been synthesized under hydrothermal conditions. X-ray diffraction analysis of three complexes show that they are isomorphic. The values of the Curie and Curie-Weiss constants of 1 are Cm=4.66 cm3·mol-1·K and θ=-21.23 K. The fluorescence spectra due to the ligand-to-metal charge-transfer (LMCT) effect. indicate that emission of 2 and 3 show obvious blue shift CCDC: 1445365, 1; 1426017, 2; 1426018, 3.
