Hydrothermal synthesis,crystal structure and magnetic property of a 3D coordinated complex Zn4(trz)4(Hnip)2(nip)·2H2On

  • 摘要: 采用水热合成法合成了一种新型的金属有机配合物Zn4(trz)4(Hnip)2(nip)·2H2On(Htrz=1,2,4-三氮唑,H2nip=5-硝基间苯二甲酸).通过X射线单晶衍射、X射线粉末衍射、元素分析和红外光谱对其结构进行表征,结果表明该化合物属于单斜晶系,C2/c空间点群,其晶胞参数分别为a=23.4973(6)nm,b=13.7631(4)nm,c=14.0652(3)nm,β=91.721(2)°,Z=4,V=4546.6(2)nm3,Dc=1.805mg/m3,Mr=1235.25,μ=3.285mm-1,F(000)=2479,R1=0.0625,ωR2= 0.1720.中心离子Zn(Ⅱ)通过Htrz配体连接形成Zn1和Zn2两种SUBs,这两种SUBs交叉相连形成了Zn4(trz)44+n的二维面,最终H2nip连接这些二维层形成了一个三维网状结构.此外,该配合物的荧光性能也得到了研究.

     

    Abstract: A novel metal-organic complex Zn4(trz)4(Hnip)2(nip)·2H2On(Htrz=1,2,4-triazole,H2nip=5-nitroisophthalic acid) has been hydrothermally synthesized.The structure was characterized by techniques of single-crystal X-ray diffraction analysis, powder X-ray diffraction,elemental analysis,infrared spectra,revealing that the structure of the synthesized complex belongs to monoclinic system with space group C2/c.The cell parameters are as follows:a=23.4973(6)nm,b=13.7631(4)nm,c=14.0652(3)nm,β=91.721(2)°,Z=4,V=4546.6(2)nm3,Dc=1.805mg/m3,Mr=1235.25,μ=3.285mm-1,F(000)=2479,R1=0.0625,ωR2=0.1720.The central ion Zn(Ⅱ) is coordinated with Htrz ligands to form two kinds of SUBs about Zn1 and Zn2.These two kinds of SUBs are cross-connected to construct a 2D surface of Zn4(trz)44+n.And adjacent 2D layers are packed into a 3D network by H2nip ligands.Furthermore, the solid state fluorescent properties of complex have been investigated.
