摘要
本文合成了2-羰基丙酸-2-甲氧基苯甲酰腙锰配合物,并借助X-射线单晶衍射测定了配合物的晶体结构。该晶体属于单斜晶系P-1空间群,晶胞参数为,a=0.7925(2)nm,b=1.0529(3)nm,c=1.1069(4)nm,α=68.142(6)°,β=69.053(4)°,γ=71.292(4)°,V=0.7816(4)nm^3,Z=1。在一个不对称单元中,Mn离子是七配位,且被镶嵌在一个有微弱形变的五角双锥结构内,配合物整体呈现双核的零维结构。利用红外光谱、紫外光谱、荧光光谱研究了其光谱性质。
Mn(Ⅱ) coordination compound, Mn(o-pAMH) ( H2 O) 2 ( o-PAMH = 2-oxo-propionic acid 2-methoxy benzoyl hydrazone) , has been synthesized using solution diffusion method at room temperature. The crystal structure and characteristics of the coordination compound were determined by X-ray crystallography and thermogravimetric analysis (TGA). Single-crystal X-ray diffraction analysis revealed that the complex was crystallized in the monoelinic space group P-1 with unit cell parameters a=0.7925(2)nm, b=1.0529(3) nm, c=1.1069(4) nm,α=68.142 (6)°,β=69.053(4)°, γ=71.292(4)°, V=0.7816(4) nm^3, andZ=1. The asymmetric unit contains only one crystallographically independent manganese ion, which is seven-coordinated and exhibits slightly distorted pentagonal bipyramid geometry. The complex displays a dinuclear and zero dimensional structure. The uhraviolet and fluorescent properties of the complex have been investigated.
